I went to my root directory, Documents, where my files are stored and unchecked the ReadOnly box and clicked Apply. It ran a status update bar after the warning that it would apply to all folders and subfolders. I thought it had been done, but when I went back in to verify the Read Only box was unchecked it remained.
See Igor Leyko's earlier reply. The "Read-only" box in the Properties dialog for folders DOES NOT MEAN that the folder is "read only." Folders can not be "read only." The Read-only attribute is only used by Windows Explorer (File Manager) to determine whether the folder is a special folder, such as a system folder that has its view customized by Windows (for example, My Documents, Favorites, Fonts, Downloaded Program Files), or a folder that you customized by using the Customize tab of the folder's Properties dialog box.
The "Read-only" box in the Properties dialog for folders has 3 states: filled-in, blank, and checked.
It's "normal" state is filled-in. This has no bearing on whether anything is "read only."
If you click the box and it then shows clear and you then click the "Apply" button, the files contained within the folder (and, if you select the option, files contained in sub-folders) will have their read-only attribute cleared. Once you do this, the read-only box on the folder's property sheet returns to its filled-in appearance.
If you click the box and click it once again so that a check appears in the box and you then click the "Apply" button, the files contained within the folder (and, if you select the option, files contained in sub-folders) will have their read-only attribute set. Once you do this, the read-only box on the folder's property sheet returns to its filled-in appearance.
