Some folders of one old version Documentum on my pc couldn’t be deleted.

System tell me “Access is denied” J

Solution:

An administrator must take ownership of the folder in order to change the Access Control List (ACL) or to access the folder.

1. Folder options – View – uncheck “Use simple file sharing”
2. Right-click the desired folder, click Property, and the nclick the Security tab.
3. Click OK when you receive the following message:
   You only have permission to view the current security information on username
4. Click Advanced, and then click the Owner tab.
   Select a new owner, select Replace owner on subcontainers and objects, and then click OK.
5. Click Yes when you receive the following message:
   You do not have permission to read the contents of directory path and directory name. Do you want to replace the directory permissions with permissions granting you Full Control?
6. Close, and then reopen Properties to refresh the ACL.

Note: The permissions for this folder are now being inherited from the parent folder. In most cases you should block inheritance from the parent by clearing the Allow inheritable permissions from parent to propagate to this object check box. You will then be able to change the permissions on this folder.
