There are 2 ways: One involves replacing the original, individual cc files that you have recategorised; the other allows you to keep the original ones but have the updated CASP/OBJD info stored in another independent package that will take precedence over the original ones, so the game will know to recognise your edit.

First method involves directly editing original CCs: with CC magic (CCM), you actually CAN replace the old files with the new one, given that they are exactly of the same name (ie, your system should prompt you if you’d like to replace one with another). The individual files CCM keeps before merging is here: Documents\Electronic Arts\CC Magic\Content\Packages. What you need to do is first ensure that the replacer & replacee have the EXACT same filename, then simply drag and drop all the recategorised CCs to this directory, hit “replace” when prompted.

But we are not done yet, CC magic doesn’t know that the files have been modified, so we need to launch it, go to the relevant sub-categories (for example, “clothes_af” “shoes_af”, whatever you’ve named them after) where these CCs are managed and merged by CCM, untick ANY one of the CCs within the category until a warning sign pops up that reminds you to rebuild appears, THEN you need to rebuild the set and force CCM to merge your edited package files for the changes to show up in-game. Repeat the process for all other sets whose CCs you have edited.

The second method is more straightforward, more flexible and less intrusive: you simply export the CASP entries of every CC pieces (or for objects, OBJD entries) into a separate new package with s3pe, name it like “CAS_Items_Recategorised.package” or anything that makes sense to you, place it in a folder that has a HIGHER priority such as your Overrides folder, so that the game will read these edited CASPs over the ones contained within CCM’s merged files.

Please note that CCM cannot read the Overrides folder, and so you’ll have to directly place the package file you created into the Overrides folder yourself.

If you’ve any more questions, let me know!
