Set up Folder Monitor
Install the Paige Folder Monitor desktop app, connect it with an API key, and create monitoring rules so files dropped in a Windows folder upload themselves to a scan job — with the completed-folder guarantee explained.
Before you begin
- A Windows machine that can see the folder you want to watch
- Administrator rights on that machine to run the per-machine installer
- A Paige account that can create API keys and see the target scan job
At the end of this guide, a Windows folder feeds a Paige scan job by itself: every file that lands there uploads, gets accepted for processing, and moves into a completed subfolder — and you'll know that the move only happens after Paige has genuinely accepted the batch, which is the guarantee that makes the folder safe to trust.
Folder Monitor is Paige's desktop companion for network scanners, copiers, and any system that can drop files into a folder. It watches the folders you tell it to, uploads matching files to the scan job you pick, and keeps a local record of everything it did.
Install it
Run the Paige Folder Monitor installer — a per-machine Windows MSI — on the machine that can see the folder (administrator rights required). It creates desktop and Start-menu shortcuts and starts the app when it finishes.
The window has four tabs — Dashboard, Rules, Activity, Settings — and a status line that reads No Active Rules until you've built one.
Connect it to Paige
Folder Monitor authenticates with an API key you create in the Paige web app:
In Paige (in your browser), open the avatar menu at the top right and choose API Keys.
Enter a name for the key — name it for the machine, like
Warehouse scan PC— and click Create API Key.
Copy the key immediately. The app means it: "Make sure to copy your API key now. You won't be able to see it again!" (Losing it is not a crisis — you create a new key and retire the old one.)
Back in Folder Monitor, open Settings. Under Paige API Configuration, leave API Endpoint at its default (
https://client-api.paige.app/api/v1), paste the key into API Key, and click Test.What you should see: Connection successful. If you get "Connection failed - check your API key and endpoint," re-copy the key — and if this machine sits behind a strict outbound firewall, make sure it can reach the endpoint over HTTPS.
Click Save Changes. From then on Settings shows "A Paige API key is securely stored for this Windows account" — the key never has to be typed again.

Create a monitoring rule
A rule is one watched folder pointed at one scan job.
On the Rules tab, click Add Rule. The Create Monitoring Rule dialog opens.
Basic Information — give the rule a name that says what flows through it (the placeholder's example: "Invoice Processing").
Folder Configuration — Browse to the Folder to Monitor, then set File Filters. The default is
*.pdf, *.jpg, *.png; use wildcards like*.pdfor specific filenames, or leave it empty to take every file. Filter deliberately — a*.pdf-only rule quietly ignores the TIFFs your copier produces.
Paige Configuration — pick the Organization, then the Scan Job the files should feed.
Click Create Rule, then Enable it. The status line switches to Monitoring Active.
An enabled rule can't be edited — the edit button greys out with "Disable this rule before editing it." Disable, change, re-enable. That's a safety design, not a bug.
How you know a file made it
Folder Monitor's handling is deliberately conservative: a file is moved into the completed subfolder of the watched folder only after Paige has accepted the batch for processing — not merely when the bytes finished uploading. So the watched folder itself is your state display:
- File still in the folder — not yet accepted; check the Activity tab and the Dashboard (active uploads, queue depth, success rate).
- File in
completed— Paige has it; look for it in the scan job's batches.
Uploads retry on failure automatically (the retry count and delay are adjustable under Settings > Performance Settings, along with concurrent workers and a maximum file size). Under System Settings, Start with Windows is worth turning on for a production machine — a monitor that only runs when someone remembers to launch it isn't monitoring.
Success check: drop one test file into the watched folder. Within moments it should appear in the Activity log, move to completed, and show up as a new batch in the scan job.
