Can you elaborate on what you mean by opening up space?
If you mean how can you free up space on your flash drive …
1; You can free up space by doing it on your Xbox 360, through the Storage settings and deleting files that way.
or 2; Right click on the file in the Device Manager on Horizon and extract files and delete them that way…
If this isn’t what you meant please be a bit more clearer on what you mean
