When I used the file cleaner, it also delete the following:
boot.ini
bootfont.bin
CLDMA.LOG
hiberfil.sys
NTDETECT.COM
ntldr.
I think, that is not the meaning of a filecleaner. I used it, my fault was that i did not checked the files. So my pc did not start and i had to copy the last 2 files from my XP cd to start the pc.
How come that the filecleaner automaticaly find those important files?
