[Short Question] itemcache.wdb - create a new one

[sakyra]

Hello,

I made same experiments with my itemcache.wdb; now at some places its destroyed, i can't find items with glitchy anymore, because they're overwritten or so.. what i want to say is:
if i delete the whole "Cache" Folder in my WoW directory, will that crash my WoW or will the game create a new "Cache" folder and new files (in the chache folder) if i startup the game, after deleting the files ?

good night^^
