I have doubt in directory undeletable concept. In Windows operation system, we convert a Undeletable file or folder in to deletable by using the command as "cacls FolderName /e /c /g %username%:f". I used the same command to access the "Undeletable folders" (for example Recovery, Documents and Settings etc.,), which is present in the C: drive. It doesn't work. How they create this kind of folders. If any other ways to do this. Kindly clear me. Thanks in advance.

Those folders have the "list folder/read data" permission set to deny for everyone. Deny takes precedence over allow, so it doesn't matter what permissions you give to a user: the deny setting will overrule it. You have to remove that setting first, which probably means you also have to take ownership first. They're owned by SYSTEM.

  • so, We are having access permission only not a read/write/modify permissions. – Aerrow Sep 08 '11 at 15:33
  • To delete a folder you first have to delete its contents, and to do that you have to list its contents. The permission settings prohibit you from doing that, so you can't delete the folder until the deny setting is removed. – Carey Gregory Sep 08 '11 at 15:37
  • if any possibilities to deny the setting – Aerrow Sep 08 '11 at 15:49
  • I'm not sure I understand what you're asking. If you want to remove the deny setting you're going to need to use icacls rather than cacls. Cacls is deprecated and you really shouldn't be using it. An even better alternative is SetACL, which can be downloaded from http://helgeklein.com/. – Carey Gregory Sep 08 '11 at 18:03
