Updated September 15, 2017 Close AutoCAD 2007. To disable the write protection on the file you’re working with, the file can’t currently be being accessed by the AutoCAD 2007 software. Locate the original file on your hard drive. If you know exactly which folder it is stored in, navigate to that folder. If you don’t know the folder location but you know the name, click “Start” and type its name into the “Search” box. Right-click on the file you were working with in AutoCAD 2007. Click “Properties.” Clear the “Read Only” check box and click “Apply.” Write protection will now be turned off on the file, and you can save to the file with AutoCAD 2007. Writer Bio
