Private document filing for Windows
The document folder that sorts itself.
ORDNA recognises invoices, contracts and tax papers, gives them names you can read and files them automatically in ordinary Windows folders. All of it happens locally on your PC — with no cloud and no user account.

The same files. Finally readable.
The real problem with a pile of documents is not keeping them — it is
finding them again. And scanning alone does not solve it: a hundred
files called Scan_0001.pdf are as silent as the paper
pile they came from.

You can see what is inside a file without opening a single one.
The whole program in one picture
- On the left: your two sources. Search folder reads in a folder of your choice, subfolders included if you wish. Below it stands or, then Search mailbox: it collects the attachments from your mailbox. Once, or daily at a fixed time. You set the period — and whether the email then goes to the bin. Either run can be stopped at any time.
- On the right: your archive. An arrow leads across from the sources — the direction your documents take. All 14 document classes stand there with their count and size, and above them the path to the archive folder. Clicking the name opens the folder in Windows Explorer. Both number columns lead into the search: the count shows every document of that class, the figure under new only what has arrived since you last reset it. At the top right, Open Excel workbook opens the overview in your spreadsheet program.
- Below: searching and correcting. A search field for name, number or text inside the document, plus the filters document type, category, receipt type, period and amount from/to — and on the right the new tick. At every hit you can correct what ORDNA read, with ✏️.
- Top right: the tools. Refresh, the documents filed most recently, the filing log, settings, the manual and the language picker. The version number sits next to the name — so you always know which state you are looking at.
Three situations where it pays off
Before the tax return
“Where are last year's childcare costs, tradesmen's invoices and insurance papers?”
One search word and a period are enough: ORDNA searches names and content and shows every hit with the place it was found. The spreadsheet it keeps alongside brings the amounts along, ready to add up.
The papers are together when the tax return comes round.
When the warranty counts
“The washing machine is broken — where is the invoice?”
Search by retailer, product or date. ORDNA also finds words that appear only inside the invoice — even if it arrived as a scan.
The invoice is there when it is needed.
When you are on your own
“Which receipts came in last quarter, and what was the net amount?”
ORDNA files invoices with date and issuer in the file name and carries net, gross, VAT and invoice number in the spreadsheet. You filter by period and sum the column — every row holds a link to the receipt.
The receipts are sorted before anyone asks for them.
How ORDNA works
1Pick your documents
You pick a folder holding your PDF files or scans — the one your scanner or your phone's scanning app saves to. The folder stays registered; it is read in whenever it suits you. On request ORDNA also collects the attachments from your mailbox once a day.
2ORDNA recognises and names
ORDNA reads every document on your PC and works out what it is: invoice, contract, official notice, payslip and more. It also works out who it is from and when it is from — and names the file accordingly. Uncertain cases are put before you for checking instead of disappearing under a guessed name.
3Finding instead of searching
The documents sit in ordinary Windows folders. You find them by name, content, document class, period or amount — scanned sheets included. Spending and invoice amounts are also carried along in a spreadsheet.
Allow a few seconds per document: recognition runs on your PC rather than in a data centre — which is exactly why your document never leaves the machine.
What it all adds up to: the spreadsheet
A readable file name is only half the job: it tells you what is in
the file, but not what it adds up to. That is why ORDNA keeps a
spreadsheet in the root of your archive,
Document Overview.xlsx, and keeps it up to date by
itself: one sheet per document class, each with the
details that fit that class.
The Invoices sheet lists, for every receipt:
- date and issuer
- invoice number
- gross and net amount
- VAT
- category and receipt type
- a clickable link that opens the file
That turns filing into analysis: you filter the columns and sum the amounts. “What did we spend on childcare in 2026?” is then a filter selection and a total, not a hunt through folders — and the link in every row takes you from the figure to the receipt in one click. You open the workbook straight from ORDNA: Open Excel workbook sits at the top right of the archive card.
The workbook updates after every run that filed at least one document — unless it is open in Excel at the time.
Try it with your own papers.
No account · no time limit · no payment details
Your papers stay on your PC
Payslips, medical bills, bank statements: these are not files you happily upload somewhere. With ORDNA you do not have to.
ORDNA transmits no documents and no content to third parties. There is no user account and no cloud.
Every step — reading, recognising, naming, filing and searching — runs on your own PC. You sign in to nothing.
ORDNA only goes online when you ask it to — in exactly three places: once at first start to fetch its recognition model; when it collects your own mailbox; and when checking for a new version of the program, which is switched off by default. Nothing about you or your documents is transmitted then either — ORDNA downloads, it does not send. Otherwise it works without an internet connection.
This website does without trackers as well: no analytics services, no advertising networks, nothing embedded from other people's servers. What arises technically is set out in the privacy policy.
What you can rely on
- Your documents stay local. Nothing is uploaded to someone else's servers for analysis.
- No user account. No sign-up, no email address, no registration.
- Your original files stay where they are. ORDNA only tidies up source folder and mailbox if you switch that on yourself — off by default.
- ORDNA deletes nothing on its own. Documents read
in twice go into a
Duplikate(duplicates) subfolder — you can bring them back at any time. - Uncertain cases are put before you. What the document does not prove is not guessed. The document then waits for you, visibly, in a catch-all folder instead of disappearing under a guessed name.
- You have the last word. If ORDNA named a document wrongly, turned a date around or filed it in the wrong place, you correct it at the search hit — ORDNA then renames the file and moves it if needed. Your correction is not overwritten by the automatic recognition later.
- No surprises behind your back. If a filing folder is missing because it was renamed, moved or deleted, ORDNA says so and asks what should happen.
- Your archive outlives the program. Uninstall ORDNA and archive, settings and records remain — ordinary folders and PDF files, readable without ORDNA.
Who ORDNA is for — and who it is not for
Both belong on the same page. If your case appears under “Currently not intended for”, you can save yourself the download.
A good fit for
- private households
- single users on one Windows PC
- sole traders sorting their own receipts
- Windows 10 and Windows 11 in 64-bit
- filing into ordinary folders on your own drive
- anyone reluctant to put private papers into a cloud
Currently not intended for
- several people using it at the same time
- network drives and server operation
- Mac, Linux and smartphones
- certified company archives
- audit-proof archiving
- replacing a backup
ORDNA is a single-seat program for one PC and has no sign-in — please do not make it available over a network share. It also makes no backup copies of your archive; back that up like your other files. And whether a filing system meets statutory retention duties is something to clarify with a qualified adviser — ORDNA is not legal advice.
Will ORDNA run on my PC?
| Operating system | Windows 10 or Windows 11, 64-bit. ORDNA cannot be installed on a 32-bit Windows. There is no ORDNA for Mac, Linux or mobile devices. |
|---|---|
| Rights | No administrator rights for ORDNA itself — it installs into your user account. Windows only asks when you have one of the two additional programs installed as well (Ghostscript, see below). |
| Free disk space | Around 5.5 GB. Of that, around 350 MB for ORDNA itself, around 62 MB for Ghostscript and around 4.6 GB for the recognition model, downloaded once. Your archive needs space on top. |
| Internet | Needed for the download and for the one-off initial setup; how long that takes depends on your connection. After that ORDNA works without an internet connection — unless you have it collect your mailbox or check for new versions (off by default). |
| Memory (RAM) | There is no tested minimum figure, so none is stated here. ORDNA is developed and tested on an ordinary Windows 10 PC. |
| Additional programs | Two free ones: Ghostscript stores your documents in the long-term format, Ollama runs the recognition on your PC. The setup offers to install both — you do not have to look for anything yourself. |
Why those 4.6 GB? Because recognition runs on your PC and not in a data centre. The recognition model that reads your documents sits with you — and that is exactly what the promise “nothing is uploaded” rests on.
Who is behind ORDNA
ORDNA is developed by Eckehard Zündorf in Lichtenfels, Germany. ZUENTEC is his brand, not a registered company.
ORDNA grew out of a need of his own: the wish to have a scanned paper invoice end up in the archive as a properly named file with no further work — and the reluctance to put private papers into someone else's cloud for it.
- Support by email via the contact page; reply usually within two working days.
- Manual and recognition reference are openly available in four languages on the support page — readable before you download anything.
- Every change is documented in the change log.
Current version 0.36.0, published on 2026-08-20.
Development status and price
ORDNA is an early version and free to use at present. You need no account and no payment details. The version number deliberately starts with a 0: ORDNA is under active development and has not been tested by a market yet. It demonstrably runs on machines other than the developer's, but you are joining early — and you should know that beforehand.
There is no pricing model yet. As long as there is none, this page shows no price, no time limit and no payment details. Should that change, it will be announced on this page in good time — your archive is unaffected either way.

Frequently asked questions
What does ORDNA cost?
Nothing at present — no price, no time limit, no registration. There is no pricing model yet; more under development status. Voluntary support via PayPal is possible.
Are my documents uploaded to a cloud?
No. Reading, recognising, naming, filing and searching all run on your PC. ORDNA transmits no documents and no content to third parties.
Do I need a user account?
No. ORDNA has no user account and asks for no personal data.
What happens to my original files?
They stay where they are. ORDNA only tidies source folder and mailbox if you switch that on explicitly — off by default.
Can I open my documents without ORDNA?
Yes. The archive consists of ordinary Windows folders holding ordinary PDF files. Uninstall ORDNA and all of that remains.
Do I need an internet connection at first start?
Yes, once: ORDNA fetches its recognition model then (around 4.6 GB). After that it works offline — unless you have it collect your mailbox or check for new versions (off by default).
How long does the first big batch take?
Allow a few seconds per document — recognition runs on your PC. A big first batch takes correspondingly long. You can stop the run at any time and continue later: anything already archived is recognised as a duplicate on the next read-in and is not filed twice.
What happens if ORDNA cannot identify a document?
Then it does not guess. The document stays visible in the catch-all folder and you assign it yourself: find it, click ✏️ on the hit, put the details right. Your correction stands.
Why does Windows warn at first start?
Because the file carries no publisher signature — that is how Windows tells where a file comes from, and ORDNA does not have one yet. That is not a fault of the file. The checksum in the download section serves as the proof: a string of characters that changes as soon as a single byte of the file changes.

How to check that you have the genuine file. After downloading, open Windows PowerShell in your downloads folder and enter:
Get-FileHash .\ORDNA-0.36.0-Setup.exe
If the value shown matches the SHA-256 figure, the file is exactly the one published here, unchanged.
Windows will speak up at first start. SmartScreen reports an “unknown publisher”. The reason is a missing publisher signature — ORDNA does not have one yet — and SmartScreen also judges by how widespread a program already is. If you want to be certain, compare the checksum of the file; for now it is the solid proof. If you want to continue: More info → Run anyway. A signature is intended. It turns the unknown publisher into a named one — the message itself only goes away once ORDNA is widespread enough.
For the technically minded
Which files ORDNA processes
PDF files by default. Image files (JPG, PNG, HEIC, TIFF, BMP, GIF, WEBP — phone photos included) and Word documents (DOCX, DOC) can be enabled as well. They are converted to PDF before filing.
The archiving format
PDF/A, the standardised long-term format, with a searchable text layer — which is what makes even a plain scan searchable by its content.
How the document recognition works
Recognition runs locally on your PC: Ollama runs a language model
(llama3.1) there — what this page calls the
recognition model, downloaded by ORDNA at first
start. There is no request to any internet service and no API key.
Why ORDNA puts which document into which class is explained in the
recognition reference.
The document classes
14 classes: invoice/receipt, bank documents, tax document, contract, insurance policy, payslip, official notice, health, education & qualifications, certificates & records, correspondence, other documents — plus Encrypted for anything a password protects, and the catch-all folder for everything ORDNA cannot assign with confidence.
How the mailbox is connected
Over IMAP, the general standard for mail retrieval. ORDNA is therefore not tied to any particular provider. The retrieval can run automatically once a day; ORDNA takes the attachments and leaves your mailbox as it was.
When the recognition made a mistake
Find the document and click ✏️ on the hit. You see the recognised
details next to the document itself and can put them right —
issuer, date, amount. If a field is part of the file name, ORDNA
renames the file; you see the new name beforehand. The same window
lets you move the document into a different class or take it out
of the archive — not deleted, but moved into the
Duplikate (duplicates) subfolder, from where you can
bring it back. You work through a whole list of hits in one go:
after Apply the window stays open and shows the
next document straight away; the arrows in the window header let
you move by hand as well. Undo restores the state
you started from, and closing asks first if anything has not been
applied.
What ORDNA records about every filing
Where the file came from and that it arrived unchanged (by checksum). A maintenance run checks the archive for empty, unreadable or subsequently altered files.
Blank reverse sides when scanning double-sided
On request (off by default) ORDNA leaves blank reverse sides out — but only when two independent checks agree that the page really is empty. At least one page always remains, and the complete original is kept.
Languages
Interface, user manual and recognition reference in German, English, Spanish and French. Folder names follow the language you install in; a later change of language does not rename an existing archive. All manuals are also available to read here. If you use ORDNA in English, French or Spanish, log lines in the background still appear in German.
Where ORDNA runs
In its own window like any other Windows program — not in a browser. What ORDNA displays it produces on your PC and only for this PC; it cannot be reached from the network.
Password-protected PDF files
ORDNA cannot read them — and therefore does not go by the file name. Such files go unchanged and under their original name into a folder of their own, Encrypted.
