```bash
gotosocial admin media prune orphaned --dry-run=false
```
### gotosocial admin media prune remote
This command can be used to prune unused/stale remote media from your GoToSocial.
Stale media means avatars/headers/status attachments from remote instances that are older than `media-remote-cache-days`.
These items will be refetched later on demand, if necessary.
Unused media means avatars/headers/status attachments which are not currently in use by an account or status.
**This command only works when GoToSocial is not running, since it acquires an exclusive lock on storage. Stop GoToSocial first before running this command!**
```text
prune unused/stale remote media from storage, older than given number of days
Usage:
gotosocial admin media prune remote [flags]
Flags:
--dry-run perform a dry run and only log number of items eligible for pruning (default true)
-h, --help help for remote
```
By default, this command performs a dry run, which will log how many items can be pruned. To do it for real, add `--dry-run=false` to the command.
Example (dry run):
```bash
gotosocial admin media prune remote
```
Example (for real):
```bash
gotosocial admin media prune remote --dry-run=false
```
