Hi,
I would introduce some points which support you in Torrenting life, what is the best way to remove your file from your client.
Please use these hints:

1.Your tracker may delete file from it's site so you don't need it anymore, here is an example, https://imgur.com/P9wPZpk

2.I can support you to free non important files from your seedbox because capacity is a big challenge for ALL of us.

3.Delete files upon the tracker rules NOT as you wish, for example if a tracker needs you to keep files for 7 days along, you aren't allowed to delete files before this period.

4.(The important hint) deleting a file from client should be based on seedtime or RATIO, so you're obliged to check both parameter before deleting it, otherwise your file will be in HnR area after that so keep this in your mind.

this is a sample message of system torrent deletion, https://ibb.co/Z9fbJ3j

please take your care to delete them plus their DATA from client as shown
