Hi Benny!

Settings are log based. If you have had just one log then you have only one settings to transfer.
At Cqrlog start, in "Database connection" you will see button "Utils". Select the log you want to move settings and then press Utils/configuration/export
Save file to USB stick and you can import it to new computer.
Once you have created a new log in new computer, but not yet opened it, use Utils/configuration/import and open your file from USB stick.
If you Cqrlog starts directly to log you will find "Database connection" from NewQSO/FIle/Open or create new log.
How ever it is recommended to uncheck only "open recent log after program start" then return back with "cancel" and close Cqrlog.
On next start you will enter to "Connect database" window.

Configuration export and import is recommended to be done when there are none of logs yet opened. It works best then.

There may be some configurations like call alerts etc. that do not move with configurations.

If you are moving Cqrlog to another computer that has same database engine version that you have in old computer it is best to try first to copy
hidden folder ~/.config/cqrlog with all files and subfolders to USB stick or other media that allows moving from old computer to new one.
If you use your filebrowser for that you must set "show hidden files and folders" to see folder ~/.config/cqrlog
From command line:
cp -a ~/.config/cqrlog /your/target/portable/device
In new computer:
cp -a /your/target/portable/device/cqrlog ~/.config
This must be done when Cqrlog is not running in either computer.

If this fails you can get clean start again in new computer by deleting folder ~/.config/cqrlog there is no need to reinstall Cqrlog.

If this did not work then you have to move log(s) as full adif backup/restore and move log config(s) via utlls/configuration/export/import
After that you can look old computer's ~/.config/cqrlog folder and move almost everything but files ending ".cfg" and folder "database"
from old to new computer.
