Working with Filegroups
You can use wildcard characters in the FileName parameter (?). and *) to display or change the properties of a set of files. If the file has system or hidden properties set, you must first clear its system or hidden properties in order to change other properties of the file.

Using Archive properties
The archive attribute (+a) indicates which files have changed since the most recent backup. The Xcopy command uses the archive attribute. For more information about archive attributes and Xcopy, see.

The Recovery Console provides attrib commands with different parameters.
Example
To display the properties of a file named News86 on the current drive, type:

attrib news86

To assign a read-only property to a file named Report.txt, type:

attrib +r report.txt

For a disk plugged into a B drive, to remove the read-only property of a file in its \Public\Jones directory and any subdirectories of the \Public\Jones directory, type:

Attrib-r B:\public\jones\*.*/S

Consider a scenario where you want to create a connection to a disk in a drive that contains all the files in its default directory (except for files with the. bak extension). Because you can use Xcopy to copy only those files that are marked with the archive attribute, you need to set the archive attribute for the files that you want to copy. You first need to set the archive properties for all the files in drive A. Second, for files with the. bak extension, you want to clear their archive properties. For example, type:

attrib +a a:*.* attrib-a a:*.bak

Next, use the Xcopy command to copy the files from the disk in the A drive to the disk in the B drive. The command line option using/A in the following command causes Xcopy to copy only those files that have the archived attributes marked. For example, type:

xcopy a:b:/a

If you need xcopy to clear the archive attribute for each file after you copy the file, use the/m command-line option instead of/A. For example, type:

xcopy a:b:/m
