# I want to use TuneSmith on both my Windows PC and Mac. How can I synchronize my song catalog?

You can move TuneSmith's backup folder in your 'Documents' folder from one computer to the other.

{% hint style="info" %}
To **transfer** changes made on a **Windows PC to a Mac**, create a new backup on the PC and copy the entire folder to your Mac to replace the existing backup folder. Start TuneSmith on your Mac and choose '**revert**' in the backup dialog. This will import any new data from the backup folder and revert any matching records that are already present. 
{% endhint %}

Records that only exist in the Mac version of TuneSmith but not in the backup folder will remain unaffected. Please note, however, that customized pop-up menus of entry fields will not be automatically updated during the import of a previously created backup. These pop-up menus may be updated manually after the import is complete by clicking on the appropriate field label while holding the control (Ctrl) key.
