I don't know if anyone may need the following information but here it is
HOW TO CHANGE OWNER AND PERMISSION ON WIN XP HOME
XP Home doesn't use file permission in extended way (that says MS)
since it uses Simplified File Sharing.
So since the problem we are having comes from incorrect owner and
permission on files there seems to be no chance to get rid of the test
files or to access the backup files.
that is not true:
Reboot your Win box in safe mode (press F8 on boot) now go to your
"locked" folder or file, right click and SURPRISE the Security tab is
Just change the owner and assign the correct permissions.
open a DOS prompt, navigate to your folder and use the cacls command
I'm not a win guru, just found those info on http://www.tweakxp.com.
Hope this may help someone else.
