Creating Network Maps
The selected map or folder will be deleted without further confirmation. Note that deleting
a map deletes only the .MAP version of the map file; the .MRM version remains intact in
the assigned directory and can be re-imported at any time. (To remove lingering .MRM
files, use the Windows Explorer or any other Windows file management application.)
