Can I store my source photos in a separate hard drive F instead of the main C drive?

Yes, you can! You can drag-n-drop any photos from any hard drive into this program, you do not have to copy any source photos from your separate hard drive to main C drive.

However, this program is designed to store the project data onto your C drive, each project may need from 20MB to 50 MB space depending on the number of pages you create and number of photos you use in each project.
