Photosync copies all you photos (or other files) to a new destination folder.

It separates them into folders of the structure yyyy/yyyy_mm_dd/ in the target folder. when setting an ssh server, the target folder may exist there.

It can change the prefix from the generic "IMG_" to something you like. I use that to distinguish photos taken with different cameras, my daughters or my wifes…

Optionally a "last" symlink identifies the latest file of the last run, so not everything in the source folder is copied or checked against the target again.
