MTP folders not detected / shown as invalid

[JITivT]

Describe the bug An external drive (in this case a mobiles sdcard) connected via MTP is not shown in dupeguru's folder selection window. If the a folder on the MTP mouted drive is input manually to the dupeguru folder selection window, an error message is shown saying the "The folder name is not valid"

To Reproduce

1. Open the "add folder to scanning list" window
2. Try to browse MTP mounted drive (it will not be shown)
3. Add MTP folder location manually to "add folder to scanning list" window address bar
4. See error

Expected behavior User allowed to select a folder that is stored on an MTP mounted drive

Screenshots If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Windows 10
• Version: 1909 Build 18363.900

Additional context No option to select/mount the phone sdcard as "USB mass storage device" so that avenue as a workaround is not possible.

Manual input of folder

Just to say, I experienced this too. Ironically, dupeguru can view MTP folders quite easily from the File > Load Directories screen (to load *.dupegurudirs files)
