I just updated to Calibre 0.9.38
When I tried to open the Tweaks I got the following error message:

Traceback (most recent call last):
File "site-packages\calibre\gui2\preferences\main.py", line 282, in show_plugin
File "site-packages\calibre\customize\__init__.py", line 636, in create_widget
File "importlib\__init__.py", line 37, in import_module
File "site.py", line 66, in load_module
ZipImportError: can't find module calibre.gui2.preferences.tweaks

Update:

After restarting the computer there was no more error and I found the tweak.
auto_connect_to_folder = ''

I guess that my problems are solved and I thank you all for your help.
