Just the supplemental information; the read-only attribute for folders in
Windows XP is the new design for the following two reasons:
1. The read-only bit on a folder is meaningless to the file system. You can
still delete, rename, and in other ways mutilate a read-only folder.
2. The shell overloads this bit to mean "go and check to see if this is a
special folder", so unsetting this on special shell folders makes them
appear normal. (All customizations are lost.)
Therefore, when you bring up the property sheet page for a single folder,
the read-only checkbox will always be in the "tri-state". It still exists
for users who want to modify the attributes of the contents of the folder,
not the attributes of the folder itself. Therefore, if you change the
checkbox from the "tri-state" to either checked or unchecked, you will be
applying attributes to files in the folder (possibly recursively) but not
to any subfolders.
When you bring up the property sheet page for several selected folders, the
read-only checkbox will be checked if all folders are read-only, unchecked
if all of the selected folders are not read-only, and it will be in the
"tri-state" if some folders are read-only and others are not. As in the
single-folder case, if you change this attribute, it is only applied to
files in the selected folders. |
