save file?

so im trying to clean up my fire pro folder cause i know there is a bunch of mod stuff left there. i play vanilla 95% of the time which is why i want to clear out all old mod stuff.

im looking through my save folder and im not sure what is essential and what might be old mod stuff that i should clear out.


here is what i am seeing in my folder


unity folder
cwesavedata.dat
fp_savedata_0.dat
fp_savedata_1.dat
fp_savedatalist.dat
savedata.dat
savedata_001.bak
savedata_002.bak
savedata_003.bak
savedata_004.bak
savedata_005.bak
savedata_006.bak
savedata_007.bak
savedata_008.bak
storysavedata.dat
themedata.dat

what should be there and what is old stuff? i noticed a lot of the files havent been modified since like 2017
