Guides
The parts of FastLoupe that carry on when the window is closed — a portable copy of the library, offsite backup to storage you own, and a command line for scheduled tasks.
Three things that happen outside the main window
The feature tour shows what FastLoupe looks like while you are using it. These three pages cover the parts that carry on when you are not: a complete copy of the library on a drive you can carry, offsite backup to cloud storage you own, and a command line a scheduled task can drive.
The portable library
A maintained clone of the whole library on an external drive — photos, catalogue and previews beside each other. It opens on Windows and on a Mac by double-clicking a file on the drive.
Offsite backup to Azure
Upload originals to a container in your own Azure storage account. We host nothing and resell nothing; Azure bills you. A paid add-on, with a free trial before you decide.
The command line
Back up, check, import, maintain and update the portable copy with one flag and no window — and exit codes a scheduled task can act on.
