(especially for Microsoft Office files):

General. This screen offers all the obvious information about the
document—location, size, modification date, and so on. The Read-

only checkbox locks the document. In the read-only state, you can
open the document and read it, but you can’t make any changes to
it.

Note

If you make a folder read-only, it affects only the files already inside. If you add
additional files later, they remain editable.

Hidden turns the icon invisible. It’s a great way to prevent
something from being deleted, but because the icon becomes
invisible, you may find it a bit difficult to open yourself.

The Advanced button offers a few additional options. “File is ready
for archiving” means “Back me up.” This message is intended for
the old Backup and Restore program described in Chapter 16, and

it indicates that this document has been changed since the last time
it was backed up (or that it’s never been backed up). “Allow this

file to have contents indexed in addition to file properties” lets you
indicate that this file should, or should not, be part of the search
index described earlier in this chapter.

“Compress contents to save disk space” is described on Figure 3-
18. Finally, “Encrypt contents to secure data” is described on
“Creating a partition”.

Security has to do with the NTFS permissions of a file or folder,
technical on/off switches that govern who can do what to the
contents. You see this tab only if the hard drive is formatted with

NTFS.
