My system is running on a PC with C:\ Drive out of space. So I tried to delete some files and clean up to get more space. I found that the %Temp% (C:\Users\Username\AppData\Local\Temp) takes lots of space and tried to delete files in it. But when I open it , it alerted me with the message:

C:\Users\Username\AppData\Local\Temp is not accessible

The file or directory is corrupted and unreadable? What to do? Is deleting files from Temp harmful to computer?

What's your operating system? Win Vista/7 or XP?

Try running chkdsk C: /F

If it doesn't help try restarting to safe-mode (F8 during boot > Select Safe Mode) and try to delete files from there

UPD: I guess Microsoft actually forces you to use their tools, such as Disk cleanup

I hope that it has been improved since Windows XP, and actually DOES delete temp files...

Besides that you should try deleting restore points and stuff like that...

Offtopic: Actually I had the same problem with Windows 7 conquering my SSD's free space (WinSxS folder, Temporary files, etc...) This made me move to Gentoo Linux, now I have Windows 7 as QEMU virtual machine for few things that I don't do often...

Try this thing: Open your start menu and type cmd. When Command Line appears in list - right click it and choose Run as Administrator. Navigate to %TEMP% dir with cd %TEMP% then try to delete all files with del *.*. Something like that. –  user157378 Nov 21 '12 at 9:37
    
the result is: are you sure (y/n) –  gokul Nov 21 '12 at 9:40
    
i pressed y and the result is same as the file/dir is corrupted and unreadable –  gokul Nov 21 '12 at 9:40
    
Make sure that you are actually in TEMP folder and press y –  user157378 Nov 21 '12 at 9:41
