Files and pins are not the same thing. Files are basically named CIDs which are organized in a folder/file structure.
Do a āipfs files ls /ā to get a listing.of all files you currently hold.
You can remove them with āipfs files rm $pathā.
Also make sure to run a āipfs repo gcā afterwards. Removing files or unpin CIDs doesnāt actually remove them from your storage. You might still provide those files from your cache to the network, if you havenāt run a gc.
It just releases the ālockā on them, so if youāre running low on storage, the garbage collector is able to purge them.
To see how much is currently in your cache, take a look at āipfs repo stat --humanā. The NumObjects and RepoSize will show you how much thereās in the cache which might be pinned/added as file or not.
