If you get Access Denied in WinXP Pro you may have to “take ownership” of the file/folder before it can be accessed.
First of all go to Folder Options, View Tab and in the Advanced Settings at the end, untick “Use simple file sharing”, which will allow the Security tab to be shown in the file’s properties. Also, in Folder options, make sure hidden and system files can be viewed if the file/folder you want doesn‘t appear.
To take ownership of the file (it’s best done at the folder level), right-click it, Properties, Security Tab, add your user name, fill in all the permissions and Apply. You can now access it.
