What is Foldr?
Foldr is a file collaboration platform that puts every storage system your organisation uses behind one interface (on-premises SMB shares, OneDrive, SharePoint, Google Drive, Dropbox, S3, Azure Blob, and around a dozen others), accessible from a web browser, desktop apps, mobile apps, and through automation.
It’s deployed either as a virtual appliance you run yourself or as a SaaS tenancy. Either way, your users sign in with their existing directory credentials (Active Directory, Entra ID, Google Workspace, SAML, Kerberos) and immediately see their existing storage, with no migration, no per-user account creation, and no separate password.
The platform breaks into a handful of overlapping capabilities:
Unified storage
Foldr presents your existing file servers, cloud storage, and personal drives as one navigable space. A user opens the web app and sees their home folder, the team shares they’re a member of, their OneDrive, and the SharePoint sites they have access to, all in one tree, all browsable the same way.
Underneath, Foldr’s storage adapter layer translates between protocols. SMB, S3, OneDrive Graph API, Google Drive API, Dropbox API, WebDAV, FTP/SFTP, Azure File and Blob, Box, Wasabi: each is a different conversation, but the user-facing model is the same.

Search and document data
Foldr indexes the text of every document it can read, across every storage backend, into one query surface. Users can search by content, by metadata, or by custom fields. Structured key-value data attached to each file (vendor name, due date, total, status).
Custom fields can be filled in by users, populated automatically by Captur (Foldr’s document extraction engine that reads invoices, forms, ID documents and writes structured values back), or set by automation. Once populated they drive search filters, table views, and reports.
→ See Foldr Search setup, Custom Fields, Captur.
Sharing and collaboration
A user can share a file or folder with someone in their organisation (Hand-Out, Hand-In, Upload, or Manage permissions), generate a public link for someone outside it, or send a Secure Link that requires the recipient to set up a password before accessing. Folders can carry deadlines, hand-in folders auto-organise submissions per user, and an optional Folio licence gives external recipients a real sign-in to a personal Shared with Me view.
→ See How to enable sharing for users, Sharing files or folders with public links, Folio.
Automation. MaSH
MaSH (“Making Stuff Happen”) is Foldr’s built-in scripting language. Users write mashlets that run on demand, on a schedule, in response to events (file uploaded, mail received), or via webhook hooks. Mashlets can read and write files, query and update custom fields, send email or SMS, talk to external APIs, generate documents, and call out to LLMs.
→ See MaSH introduction and the rest of the MaSH category.
AI assistant. Grace
Grace is the AI assistant that lives inside the web app. She can answer questions about files, run searches you describe in plain English, take action on your behalf (move, share, tag, redact), generate documents, and write MaSH automations from a natural-language description. Grace runs against your storage with your permissions. She sees what you see, never more.

Apps
A user reaches Foldr from:
- A web browser. The primary interface for most users.
- Foldr for Windows and macOS desktop apps. Mount Foldr as a drive in Explorer / Finder, with optional Office integration and offline file sync.
- Foldr for iOS and Android mobile apps. Browse, preview, scan, annotate, and upload from a phone or tablet.
- The API and webhooks. For programmatic access and integration with other systems.
All apps share authentication, all see the same storage, all respect the same per-share permissions.
→ See the Apps category for setup, deployment, and troubleshooting.
