I need permission to move or copy or open or really do anything to this one .dll file which I NEED to move, it's located on a mounted .iso.

I've tried

  • using administrator log in and it won't allow me to do anything with the file
  • takeown in CMD
  • looking at the folder properties that the file is contained in for security settings, and the folder only has "general","sharing","customize" tabs.
  • every answer to this question i've seen, and none have worked

Some extra info: Yes, the security tab is visible in other folder properties

It would be helpful to know how is the .iso mounted - Daemon Tools? VCDControlTool? built-in Windows feature? – grawity May 22 '11 at 12:28

An ISO-9660 filesystem is usually read-only, and the only way you can modify it (whether it is a CD or an .iso image) is to extract all files and rebuild, or to use a tool such as WinImage or MagicISO.

(The "Security" tab is not visible because ISO-9660 does not support it.)

If you cannot even read a file, it might be caused by

  • another program keeping it open and locked; try Process Explorer or Unlocker;
  • an antivirus gone mad;
  • the filesystem being corrupted.

Unmount the image and open it in MagicISO or WinImage, then see if you can access the file.

I'm curious, how did you deduce that the filesystem is ISO-9660? – Sathya May 22 '11 at 12:28
@Sathya: Quote from the question: "it's located on a mounted .iso." (It may be a UDF image of a DVD, yes, but the same restrictions apply: read-only and no Windows-compatible ACLs.) – grawity May 22 '11 at 12:30
d'oh - missed that line. – Sathya May 22 '11 at 12:31
problem solved! I opened it in WinImage and it worked immediately, thank you very much! – Ali May 22 '11 at 12:31
