I always have problems finding the date I downloaded something these days, I just get modified on such and such when all I did was open the folder it's in!
when I download a new hack (or a new version) it goes in a new subfolder for that hacker/modder and I now put the versions # or the date I downloaded it as part of the name of the subfolder, found it helped me keep track of them better cause I always keep the older versions "just in case"
