Guidelines for assigning snapshot views to drives (Windows)
If your makefiles or other files require absolute paths with a specific drive, assign your view to a drive. Depending on the configuration of your computer, two methods are available for assigning snapshot views to drives.
Creating a shared directory and assigning it to a drive
From Windows® hosts, you can create a shared directory and assign it to a drive. With this method, you and other team members using Windows hosts can access a view through My Network Places or Network Neighborhood, but the performance is slightly slower than if you use the subst command to assign the view to a drive.
From Windows® 95 or Windows® 98 hosts, you can assign a shared directory to a drive only if the directory is on some other host; for example, you can use this method to assign someone else's view to a drive. If your view is on a Windows® 95 or Windows® 98 host, you must use the subst command to assign your own view to a drive.
Using the subst command
Assigning a view to a drive with the subst command provides slightly better performance than making the snapshot view a shared directory. However, only shared directories are accessible through My Network Places or Network Neighborhood. To assign your own view to a drive on Windows® 98 computers, you must use the subst command.
