I don't see why it would be grayed out.. try using the attrib tool. that is
only if you know DOS commands, and if you would like to learn here are some
tips:
"cd" stands for change directory.
"cd\" means change to the root of the directory
"attrib" stands for attribute. it allows you to add and remove attributes
for files
here is an example of how to make a file hidden.
pretend this is the file (C:\testfolder\file.jpg):
Click Start, then Run, type "cmd" and press enter.
(after each line, press enter)
C:\Documents and Settings\User>cd\
C:\>cd testfolder
C:\testfolder>attrib +h file.jpg
To find out how to use it, type this command:
C:\testfolder>attrib /?
Do not type in the WHOLE thing, just whatever comes after the ">".
Everything else is automatically generated by the computer.
