I noticed something strange last night and wondered if there's any tool on Backtrack to manipulate this. I have a seperate limited account on my pc for gaming and internet (so not as many virus's or worms get installed, as i'm not running root). I did notice years ago that as you create the account, you could limit access to other users files. But last night when i ran a defrag, from this limited account, it accessed these apparent inaccessible files. Is there a tool that could manipulate this and use the defragger to access the files so that i can gain access? I did do a bit of experimenting with my programs and its only the defragger (Piriform Defraggler) that can do this. Nothing else has permission to access them. Not even my anti virus. I am using Windows 7 build 7600 for those that need to know. Thanks in advance
