- Linux
- Java 17
- (Or just Docker)
You can run the JAR file directly, or use the Docker image (https://hub.docker.com/r/bingud/filemat).
Filemat is currently not available on apt.
Make sure your machine has Linux and Java 17 installed.
Download the JAR file from the releases section.
Use this command to run the file with Java (change the filename according to the JAR file you downloaded):java -jar filemat.jar

Run Filemat as non-root
Create a dedicated linux user for Filemat. Create a group and add the Filemat user. Also add your other users that should keep access to the file.
Set this group (and group permissions) for all files that Filemat should manage.
It's possible to run Filemat as root — the most sensitive files are fully blocked by default — but it's discouraged for security reasons. -
Limit file access
If running Filemat with Docker, choose specific folders that Filemat should be able to access,
instead of exposing your entire filesystem through a Docker volume.
It's easy to configure volumes later with Docker compose.
Files must be explicitly configured to be exposed, so that Filemat can allow users to interact with them.
The application data folder is fully blocked by default, and can only be made accessible using an environment variable.
Symbolic links can be toggled.
In order to make any of these changes through the web UI, a user must have CLI access to the Filemat deployment to authenticate.
Environment variables override these settings.
