Deleting files-Hack Works?

After reading the forums for a lil while, I see that some users actually delete the ending banner , CAV file from the combat arms folder, and some other files the HShield folder, can someone tell me all the files there supposed to delete.

we need to clean out your failed attempts log! in your CA folder (C:\Nexon\Combat Arms) you must DELETE the files- CAV.exe, EndingBanner.exe, rwdata2.bin, and all Debug(blah blah blah).txt files. NEXT is INSIDE your HShield folder (C:\Nexon\Combat Arms\HShield) there are two .v3d files that also need DELETED they are v3warpds.v3d and v3warpns.v3d.
