Mounted Folder

Scan a folder of documents, spreadsheets and images — on this computer, or mounted into the cluster.

The simplest source there is: point Classifyre at a folder and it scans what is in it. On the desktop application that’s a folder on your own machine; in Kubernetes it’s a volume mounted into the cluster — a file share, a NAS export, a migrated archive.

What you need to connect

A path, as seen by the machine running the scan. There are no credentials: the scan reads the filesystem with the permissions of the process doing the scanning — the desktop app’s, or the scan job’s in the cluster. That’s the whole security model, and it’s worth being deliberate about which folders you expose.

In the desktop application you pick the folder with a normal file browser.

What Classifyre reads

Every file below the folder, subject to the traversal controls:

ControlWhat it does
Max depthHow far below the folder to descend
Include hiddenWhether dot-files and dot-directories are scanned
Follow symlinksOff by default — link loops are not detected
Extension allow / denylistNarrow it to the file types you care about

Shared behaviour · File and object sources

Every object in the folder becomes one asset. What it is — a PDF, a spreadsheet, a screenshot, a video — is worked out from the bytes themselves, not from the file name, because storage systems routinely label everything as generic binary data. The full list of readable types is on File Formats.

Files hidden inside other files are pulled out and scanned in their own right: images embedded in a document, and every member of a ZIP, TAR, 7z or RAR archive. Images, audio and video need OCR and transcription switched on before their content can be read.

Large objects are streamed rather than loaded whole, so a multi-gigabyte file costs disk rather than memory, and only the part a sampling window asks for is read.

Files in this folder are read with the shared file pipeline: see Supported File Formats for everything it can open, and OCR & Transcription for reading text out of images, audio and video.

Lineage

Lineage

This source records no lineage. Nothing in the system it reads describes data moving from one place to another, so no FLOW edges are produced. Related items are still linked — see Lineage & Relationships for what those links mean and how they differ from lineage.

Worth knowing

  • A mounted network share behaves like a local folder, so SMB and NFS exports can be scanned without a dedicated connector.
  • Deleted files are noticed. A file that disappears between scans is marked deleted, and the findings it produced can be resolved automatically.

Configuration

Beyond the fields below, every source also has the settings shared by all of them: the sampling strategy, the detectors to run, the scan schedule, and the compute limits for its scan jobs.

Required

Without these, the source will not save.

FieldTypeRequiredWhat it doesDefault
requiredobjectYesno extra properties
pathstringYesAbsolute path of the folder to scan, as seen by the machine that runs the scan. On desktop that is this computer (for example /Users/jane/Documents). In Kubernetes it is the scan pod, so the folder must be mounted into CLI jobs first via the chart's `api.localFolders` — then use the `mountPath` you gave it there (for example /mnt/corpora/invoices).

Secrets

Stored encrypted and never shown again after you save them. See Configuration & Fields.

FieldTypeRequiredWhat it doesDefault
maskedobjectNoA folder scan reads the filesystem it runs on with that process's own permissions — the desktop app's, or the CLI job pod's. No credentials are required.no extra properties
