How to Get Rid of Write Protection on a Fileby Robin Coe
The read-only option for computer files is an effective way to write-protect important information stored on your computer. If a file has the read-only attribute, no one can delete or edit it. However, transferring files between computers or from an external storage device such as a CD or flash drive will automatically set the file to the read-only option. But a write-protected file can easily be "unlocked" to remove its write protection when needed.
Right-click on the file name for which you want to remove the write protection property.
Scroll down the menu and select "Properties."
Click the "General" tab in the dialog box. At the bottom of the menu, next to Attributes, there is a check box labeled "Read-only" and another marked "Hidden."
Deselect the "Read-only" option by left-clicking the box. You will now be able to edit the file.
