Cant delete any file or folder on my external USB Hard Disk

[ashehzad]

I have a 40GB external USB hard disk where I backup my files. Now when I am trying to delete any file or folder I get the message

Cannot delete "file name":Access is denied
Make sure the disk is not full or write-protected and that the file is not currently in use

There is also a hidden foler $AVG8.VAULT$ which is unknown to me.

I am using windows xp sp2
thanks for help.

the external has NTFS on it and permissions restrictions.

login to an admin account
plug-in the external HD
dbl-click My Computer
find the external HD->right-click->Security
add <Everyone> to the permissions
then set Full Control on Everyone

click REPLACE permissions and Apply
(will take a few minutes to complete)
