you can always do this yourself, open a DOS promtp, or Command Prompt. go to whatever directory you want to remove the READ-ONLY attribute, and type attrib -R /S
the - R clears READ-ONLY, also,
-A clears Archive bit
-H clears Hidden attribute
-S clears System attribute
to turn ON the bits, use a + switch
the /S tells the command to process all files in the specifed path.
