Help! I'm having the same problem too. I've extracted a foobar.exe file wanting to see what are the contents but all I get is a folder with several files with single alphabets as names & directory (no file extensions!) and these files cannot be opened. Since I cannot see what these files are, I tried to delete the extracted folder but I keep getting "An unexpected error is preventing the operation...blah blah blah. Error 0x80070091: The directory is not empty." I'm using Vista Ultimate x32 and tried using the Safe Mode method but still cannot delete this darn folder! I also tried changing the security permisson but still unsuccessful. WTF?! Will the developer of this program take responsibility and provide a solution to this please? Thanks
