How to Make Undeletable Files and Folder in Windows 10

Today we are going to show you a very important thing that every Windows user should know and that is “How to make files or folders undeletable in your windows 10”

It may be very useful to some users. Especially if you have something important on your computer, for example, a document, some top priority files or even your important work files. You can use this method to make that folder or file literally undeletable so you can have that peace of mind.

Let’s get started.

First, you need to locate the file or folder you want to make undeletable. In my case, I have a sample folder created for the demonstration. It does have some files inside, but we are going to make the entire folder undeletable. It will protect the folder and files inside from any accidental delete. The procedure is the same for both files and folder so you can apply this to any kind of situation.

Now again go to Group or user names and this time select the second one and as we did before, just click on Deny to full control. Finally, you have to go to the group or user names once again and this time select the third one and deny the full control permission to that as well. If you have more Groups or users, you can simply continue the process to all of them one by one. Once you do that, click on Apply, Yes, Ok and Ok and that’s it. Now we have officially made this folder undeletable. To prove it, let’s try deleting it, and you can see it’s undeletable!
