Type a short folder name and click Create folder. Empty folders are saved and can be used later.

Click image cards to select them. Selected images are highlighted and also appear in Images to attach.

Choose a folder from Move to, then click Move selected. You can also drag an image card onto a folder.

Folders are labels on images, not server directories. Choose Unfiled to remove a folder label, or delete a folder to move its images back to Unfiled.
