Let's get this cleared up fast. Admins are not Gods. They can change permissions, take ownership but must obey read-only and things such as "permissions."
Yes, again you can change permissions but an Admin account does not mean the rules are put aside.
To fix this, google "XP TAKE OWNERSHIP."
The rest of the message says "Make sure the disk is not full or write protected and that the file is not in use"
In Folder:Properties, the file shows as 'Read Only'. Unticking this box followed by the option to do the same for all folders and subfolders, then using 'Apply' was unsuccessful, as when I tried to rename the folder after doing this,the message reappeared, and the folder was again 'Read only'.
As Administrator, my understanding is that I have full permissions under the Security section of Properties, which appears to be the case, as all boxes are ticked.
The path is as follows:- C:FOLDER:Subfolder1
Sub..1 cannot be renamed. It contains four additional folders, (each with loads of subfolders),of which 3 can be renamed, whilst the fourth one cannot, with the same "Access denied..." message appearing.
Sub...1 is a large folder (~25Gb), and my hard drive shows 58.8Gb free space.
Sorry for the lengthy post, but I've tried to include everything. I'm not that clued up, so may have missed something obvious to others.
Hope someone can help.
