Cannot Upload Large Files

Add to docker-compose.yml:

environment:
  - MAX_UPLOAD_SIZE=500M

Backup data

tar -czf tinyfilemanager-backup.tar.gz data/

File Permissions

If you cannot upload files or edit files, it is usually a permission issue on the host machine. Run this command on your host (inside the tinyfilemanager folder) to allow the container to write to the data folder: tinyfilemanager docker compose

# Makes the data folder writable by the container
chmod -R 777 data

(Note: 777 is the easiest for personal servers. For stricter security, use chown to match the container user ID, usually www-data / ID 33). version: '3

Option 2: Advanced Setup (MySQL + Docker Management)

Use this if you want a dedicated database (better for many users/large directories) or if you want Tiny File Manager to be able to manage your Docker containers. Cannot Upload Large Files Add to docker-compose

6.4 Run as Non-Root User

The official image already runs Nginx and PHP-FPM as www-data (UID 82). But ensure mounted volumes have correct permissions:

chown -R 82:82 ./data

7.2 TFM + Jellyfin / Plex

If you run a media server, mount your media folders into TFM to upload/manage movies, subtitles, and metadata directly from the web.

6.6 Disable PHP Execution

If you don’t need to execute PHP files, you can mount a custom Nginx config that serves .php files as plain text or denies them.

Notes and recommended changes

• Change TFM_PASSWORD to a strong secret before exposing publicly.
• Map a host folder (./data) to persist files. Ensure correct permissions (www-data:www-data or UID/GID matching container).
• Expose port 8080 only if you need external access; for public deployments put it behind a reverse proxy (Traefik, Nginx) with TLS.
• Use the official or trusted image; the example uses tony2001/tinyfilemanager — verify image source and tags.
• You can disable delete/edit/upload by setting the corresponding environment variables to 0 for safer read-only access.
