When you would like to bulk select multiple assets from multiple albums, this is possible using my selections.

While bulk selecting assets from a location, click the 'Remember Selection' icon:

You can navigate through other albums/locations within your library and remember the selection.

The selections will all be available within the My Selections album:

Within here, you can bulk select your assets to perform actions.

You can also export your selections as a Contact Sheet. When selecting My Selections in the Folder Tree, the option to export your selections as a Contact Sheet will appear at the bottom of the Folder Tree. Click here to learn more about the Contact Sheet feature.

Note: Your selections WILL clear out automatically upon logout. 

To remove assets from my selections, select the files, and click remove.
