# Providing Additional Files to Docker
SecretVM lets you attach an optional .tar archive containing extra files your workload needs at runtime.
When provided, the archive is automatically unpacked into the ./usr/ directory inside your SecretVM environment.
These files become available to Docker Compose and can be mounted into your containers just like any local path.
#### How it works
1. Upload a .tar archive.
2. SecretVM extracts it into: `./usr/`
3. You can then reference any file inside that directory via standard Docker volume mounts.
Example:
`volumes:`
`- ./usr/myfile:/app/myfile`
#### Typical Use Cases
* Supplying config files or secrets that aren’t stored in the image
* Bundling auxiliary scripts or models
* Including static assets needed at runtime
\
This feature is optional and only needed for advanced workloads requiring external file bundles.
