If you share your computer sometimes with your kids or let other people use it from time to time, something you probably don’t want them doing is moving around or deleting files and folders they shouldn’t be. Even if you have no problem with others accessing your files, you probably don’t want them making changes to anything. It can be a similar situation if you want other users to be able to access all areas of their own computers they need to, but not to easily have the option to copy, rename or delete any files.
Of course we could encrypt the files if we don’t want them copied off the system because cracking an encrypted file is not as easy as point and click. The easiest way to get around this problem is to actually disable the option for users to be able to manipulate these files without affecting the ability to read them. An obvious solution is to stop the user having access to cut, copy, paste, delete and rename. Here are 3 tools that allow you to do this and also a couple even have their own self protection measures to stop average users from re-enabling the options without your say so.1. M File Anti-Copy
The newer versions of M File Anti-Copy are full shareware releases, but the older version 4.0 was freeware. All you need to do is to enter a master password after installing the program, and you can protect your files and folders by clicking the Activate button. Once Anti-copy has been activated, you will find that you can actually click on the cut or copy entries in the context menu and obviously use the keyboard shortcuts (Ctrl+X/Ctrl+C). But when you try to paste the object, the Ctrl+V shortcut does nothing and the Paste command in the right click menu is grayed out. Copy and paste is also disabled in text or document files as well.
To copy or move a file when the Anti-copy program is activated, there is a built-in File Copier and File Move function for you to do that so that you don’t need to deactivate the protection first. Another feature is the Anti-Delete Protection which opens a window where you can add several files, and after the Protect All button is clicked, they will be protected from deleting or renaming by the average user.
M File Anti-Copy has some interesting functions to try and protect itself from being tampered with while protecting the files. By default, Task Manager and the Registry Editor are both disabled when the Anti-copy is active. In the Options Lock tab there are additional things to disable such as Folder options, Search and the Run dialog. These options are actually what some forms of malware do to prevent you tampering with them and users are normally looking for ways to repair these disabled functions, not implement them on purpose.
When File Anti-Copy has been activated, a new process called svchost.exe will run which you can recognize in a Task Manager tool because its description is also svchost.exe. Terminating this process will allow you copy and move files/folders again. When you enable File Anti-Delete to protect your files from being deleted or renamed, a new process System.exe is created with the description again being its name. Killing system.exe will allow you to rename and delete a file even if the protection is active. Of course, experienced users could simply use something like Process Explorer to delete these processes when Task Manager is still disabled.
