In SimPE Preferences under file tables i have probably over a hundred missing folders some checked with blue checkmarks some unchecked. many of them say absolute so i have no idea what ep to put them under. I'm a beginner and I'm so lost, any help appreciated.

I originally pointed SimPE to the legacy file paths but SimPE keeps wiping them out

What do you have under "System folders" in SimPE?

I originally had this set up properly but it ended up getting wiped out when i opened it somehow. I cant remember which stuff pack is which.

EPs go by pack names and numbers, so you can follow the list for the EPs (EP1=Uni, EP2=Nightlife, etc.)

SP9/EP9 is M&G (can vary what it's called)

For the SPs,
FFS= SP1
Glamour life = SP2 (mine says "Glamour life" with the UC)
Celebration = SP4
H&M = SP5
TSS = SP6
K&B = SP7
IKEA = SP8 (Legacy doesn't have IKEA by default)

Not sure if there's a "Store Edition" for Legacy, so you can probably skip that one.

Thank you! It's annoying because I already set this all up when I installed legacy collection and somehow everything got wiped. I'm trying to extract textures from the base game to make custom content and it's just not letting me. Hopefully setting this up again will work
