They seem to be reparse points: ``` C:\Users\*****\AppData\Local\Microsoft\WindowsApps>dir /a Volume in drive C is OSDisk Volume Serial Number is CCED-E58F Directory of C:\Users\karth\AppData\Local\Microsoft\WindowsApps 04/16/2020 12:51 PM <DIR> . 04/16/2020 12:51 PM <DIR> .. 04/16/2020 12:51 PM <DIR> Backup 03/10/2020 01:15 AM <DIR> CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc 03/24/2020 07:48 PM 0 debian.exe 04/14/2020 11:59 PM 0 GameBarElevatedFT_Alias.exe 04/16/2020 12:51 PM 0 idle.exe 04/16/2020 12:51 PM 0 idle3.8.exe 04/16/2020 12:51 PM 0 idle3.exe 11/09/2019 02:15 AM <DIR> Microsoft.DesktopAppInstaller_8wekyb3d8bbwe 11/13/2019 10:09 AM <DIR> Microsoft.MicrosoftEdge_8wekyb3d8bbwe 04/14/2020 11:59 PM <DIR> Microsoft.XboxGamingOverlay_8wekyb3d8bbwe 11/13/2019 10:09 AM 0 MicrosoftEdge.exe 04/16/2020 12:51 PM 0 pip.exe 04/16/2020 12:51 PM 0 pip3.8.exe 04/16/2020 12:51 PM …
