Sometime we need to set some files or all files of a folder to read only. Read only files cannot be modified. These files can only be copied, moved, renamed, or deleted. In this tutorial I will explain how to set and unset read only attribute to particular files or all files of a folder.
Select the file and right click and then select “properties”. If you want to set multiple files, select multiple files and then right click and then select “properties”. If you want to set read only attribute to entire folder, select that folder and right click and then select “properties”.
Similarly for folder.
After clicking “Apply” button a popup will appear, select “apply changes to this folder, sub-folders and files” And click OK buttons.
Now your files/ folders are set to read only.
Follow the above steps, and un-check the “Read-only” box, and click Apply and then OK buttons.
