Viewing Backups
When you mark a file to be part of a backup, an icon is
overlayed on the lower right hand corner. However, this is
only viewable if you're looking in the directory containing the file.
Other marked files in other directories can't be seen.
To show all the files in all the directories, TagNBag
provides a Shell Namespace
Extension. It is labeled TagNBag Backup.
It contains a virtual
directory that represents what the backup set would look
like on the target. It is labeled To back up.

As files in the regular filesystem are marked, they appear in the root directory of the To back up virtual
directory. From there, they can be moved or copied to subdirectories,
just as in the real file system. In the detail view mode, the
size and date are taken from the time that the files were marked.
