Ever faced a situation when someone used your system and copied some data which you didn’t want to share with him? Almost all of us face this situation. We all have some private data or some software which we don’t want to share with others. But we can’t do anything when our friends or relatives copy them from our system.

Here we are going to share a very small and portable application which does the job perfectly.

Now whenever someone will try to cut, copy or delete a file/folder, nothing will happen. No keyboard shortcut will work. So your data would be safe.

1) Stopper

Stopper is about as simple as it gets because there is no GUI interface, no options to configure and nothing to install. Simply run the portable executable and the program will just sit in the background and stop you clicking on the Paste context menu entry or the Ctrl+V shortcut to paste files, folders or blocks of text etc inside programs. Also Stopper will prevent files being deleted although they can still be renamed.


How it work:

Enable Stopper: Simply just open, it run in background. User Can’t copy, cut, move, delete or rename any file or folder.

Disable Stopper: Open Task Manager -> Click on Processes Tab -> Search Stopper.exe -> click on End Process.

If the above process not work restart the explorer.exe. how…
  • Open Task Manager
  • Click on Processes Tab
  • Search explorer.exe
  • click on End Process
  • Go to File Menu, Click on New Task (Run…)
  • type explorer, Click ok
  • Done, Now the Stopper.exe disble

2) Prevent

Prevent is a small tool, the configuration options are limited only to setting up a shortcut key which can be used to exit the program and return the copy and delete functions to the system. Prevent is able to disable keyboard shortcuts and gray out the context menus/buttons for cut, copy, paste, delete and rename. Also, the Copy to, Move to and Send to functions are disabled as well.

As a self protection measure, Prevent does a couple of things to the Windows Task Manager to stop anybody killing its process. Firstly the End Process button is removed and secondly the context menu is disabled when you right click on a process. This makes it almost impossible to kill Prevent within Windows Task Manager and you would have to use a third party task manager, the built in Windows Taskkill command line tool or the hotkey if you defined one.

How it work:

Enable Prevent: Open the Prevent Setup file  and install it ->  Define a key to stop the Prevent from running


Click on Activate, now it disable the copy, cut, rename, delete and send to option from right click.


Disable Prevent: Just press the Hotkey you define. In my image I define Ctrl+Q.
