Windows - File System


File (System, Transfer, Storage) in Windows

For simple management in DOS, see:



Microsoft’s security model doesn’t permit to give ownership to someone, only to take it. That way an admin (or otherwise privileged user) cannot take ownership of a file inaccessible to her directly, access or modify it, and give it back to the original owner without notice to the original owner.

  • cacls
REM /t means "apply change recursively"
REM /e means "edit existing DACL". 
REM     Omitting this will overwrite the existing DACL.
cacls c:\temp\Test /t /e /g Everyone:f



In Windows, a file is considered an executable file if its extension is in the pathext environment variable.

There is no notion of executability in the file permission as on Linux.
