I realized that some mods(mainly clothes) are problematic for me or just useless and I dont want them in my game, but I have one huge file and single mod usually consist of few files. Is it necessary to make another compression (time-consuming) or manually search every part of mod(time-consuming too and tiring)(idk what i can delete, and it wont mess other mods)? Does maybe exist program which allows to delete/blacklist mods during using CAS?

If I understand correctly, you have a merged package and you want to remove some CC from it?

If you still have a copy of the individual files, you can use them to delete them from your merged package.
NonaMena made a tutorial that explains how to do it.

As for Blacklisting, you can do this in CAS using Nraas MasterController. You can get more info in this FAQ.
Note that If you want to be able to Blacklist even outside of MasterController's Edit in CAS, you'll have to get the Integration module.

Yes, that's what I mean. I'm sorry for my unprofessional vocabulary.

Fortunately I keep individual files and NonaMena's solution works. I'm so happy, that's easy. Thank You so much! And I'll try blacklisting with MasterController too ^-^
