Unc path vs mapped drive windows#
UNC paths can be added to Windows apps in service mode via CFPclient. The drive should enumerate in the drive listing once you have done this. Adding a drive to the Windows app (service mode):.You’ll see your new drive in the Disk or Share enumerator.
Create a new system (Windows Drive or Share) and select the Win app for Point of Presence. Map the drive as a letter or as a network share. Adding a drive to the Windows app (desktop mode):. Once systems are auto created in CFP for each of the drives, you can switch the Win app to run as a service, and all of the mapped drives will convert over to UNC paths automatically. The user who maps the drives must be the same user who installs and runs the Windows app. The easiest way to connect all of your drives, regardless of whether you are running in desktop or service mode, is to map them as letter drives before the Windows app is installed. When the Windows app is installed, it will search for all of the mapped drives for the currently logged in user and will automatically generate a system for each mapped letter drive and network share for that user.īest practices – Adding Drives on the Windows App:. The Windows app converts all drive letters to UNC paths. In service mode, you can explicitly specify which user the app runs as. In service mode it will continue to run after the user session ends. The Windows App can run in application mode or in service mode. Ad-hoc drive mappings should be done from an elevated Administrator command prompt. The consequence of this is that you will most likely not be able to access a drive mapped ad-hoc from a user session (via Windows Explorer or net use. Windows maintains separate drive mappings and file share authentications for each user session. This is typically a separate Windows session from the user session. The CFP Windows App normally runs as a local administrator (via “elevation”). (Is “Z:\Backups\Backup1.zip” the same as “\\home\Personal\Backups\Backup1.zip”).We aim to make it as easy as possible to access network shares, but there are some complexities to be aware of. I’m using this function so that I can verify that given two file names, I can be assured that they are pointing to the same physical location.

Unc path vs mapped drive code#
Here’s the C# code I wrote to do this: using System If you want to store for example a UNC path to a file rather than a drive letter, you’ll need to convert the “Z” drive to the corresponding UNC root path. In this example, the “Z” drive is mapped to a “Personal” folder on a server named “Home”. For example, a drive letter such as “Z” might be mapped to a network share: Occasionally you might have the need to convert a mapped drive letter to a UNC or network path.
