Can't open files from local folder mapped as a network drive

[SASJedi]

To emulate a production environment, I’ve mapped the C:\public folder on my laptop as the S: drive. Since the update to Noepad++ 8.1.5, I am no longer able to open files from that location in Notepad++. None of these techniques work:

1. Right-click and choose Open in Notepad++ from the context menu
2. Double-click a .txt file in File Explorer (Notepad++ is my default for text files)
3. From the File menu, the S: drive is not even browsable.

Any ideas on how to fix this?

@SASJedi ,

Experiment:

I just created the following test cases:

1. net use z: \\remotemachine\path && explorer z:
2. subst y: c:\path\to\folder && explorer y:
3. net use x: \\localhost\C$\path\to\folder && explorer x:

Confirmed that Windows Explorer opened for each of those three mapped drives.

Used the explorer for all three of those mapped drives, and did a double-click to open something.txt or similar into Notepad++ (same works for right-click-and-choose rather than double-click): all three successfully opened, and showed the right X: or Y: or Z: prefix in the full path in Notepad++ title bar. Closed those three files.

Inside Notepad++, use File>Open, and browse to a file in each of the Z:, Y:, and X: drives, and successfully open them.

Sorry, I cannot reproduce.

here’s my ?-menu > Debug Info

My guess is that Notepad++ is opened as Administrator for you, because Admin doesn’t see the normal-user’s mapped drives, IIRC. (My I.T. department doesn’t allow me to open Notepad++ as Admin, so I cannot test to confirm, sorry.) It’s really easy to see whether Notepad++ is running as admin by looking at the title bar of the NPP window, or by the ?-menu’s Debug Info entry.

Fascinating! It WAS opening in Admin mode. I fixed that - and it’s working. Thanks SO much for taking the time to explain.
