The problems are well known.
But you have to set it up correctly, and Windows also offers enough in-house tools for that:
Create a textfile, call it something like mount nextcloud on drive Z.bat with the following content:
@echo off
cls
echo Delete existing connections
net use * /delete /yes
echo Connecting network drive
echo.
net use Z: \\%your-nextcloud.com%@ssl\remote.php\dav\files\%user%\ /user:%user% %password%
echo.
echo connection successfull
in this file you have to replace
%your-nextcloud.com% with the url of you nextcloud server,
%user% with the user you want to connect to
and
%password% with the app password that you created for this mount in your /settings/user/security section on the webfrontend.
Now you can add it to your autostart folder as follows:
Press the “Windows” key + R together,
enter shell:startup
Drag the batch file into the folder.
Alternatively, you can add the file to the registry’s autostart mechanism in:
\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
If you don’t want it to auto mount, you can simply keep the file somewhere and as soon as you double klick on it, your drive wil be mounted.
