+The value of `keep_days` can have a significant impact on the number of objects stored on the filesystem or in S3.
+A lower value of `keep_days` will allow the garbage collector to remove more objects, reducing the storage requirements as well as the number of objects.

+### Removing FS Objects
+
+SeaTable uses Seafile to store assets that have been uploaded to bases. Internally, Seafile uses a [data model](https://manual.seafile.com/13.0/develop/data_model/) similar to Git, which consists of `commit`, `fs` and `block` objects.
+By default, `seatable.sh gc` will only remove garbage or unreferenced `block` objects. Objects of type `fs` (filesystem) won't be removed.
+
+You can add the `--rm-fs` commandline option to also remove garbaged or unreferenced `fs` objects:
+
+```bash
+docker exec seatable-server /opt/seatable/scripts/seatable.sh gc --rm-fs
+```
+
+!!! note "Ofelia add this commandline option by default"
+
+    If you use the included [Ofelia](../installation/components/ofelia.md) configuration to run the GC process, the `--rm-fs` flag is added by default.
