My old PC is broken and I forgot to export RD Tabs configuration. 🤦
Is there any way to retrieve it from the disk (i.e. a file or something else)?
Thanks

You can, but you will lose saved passwords because it's protected by Windows cryptography that is tied to your user account. Meaning you have to be logged in as your user to decrypt the password data.

%localappdata%\Avian_Waves\RDTabs.exe_SomeLongGUID\2.x.x\user.config

Just take that "user.config" file and put it in the same place on the new PC. RD Tabs will figure out that it can't decode the passwords and it will clear the field.
