I have reasonable experience using iPad (linked to Windoes device) but I am new to an iMac. In the past I have been accustomed to successfully syncing my photos from the Windows device on to our iPads, retaining the folders/albums with their descriptive names. My most recent syncing, from the folders now on iMac, lost the folders. Also I am trying to get the photos, in their folders, into Photo on the iMac. Can I readily achieve what I am trying to do? We have about 75000 photos, of which about 25000 in 200 folders are the ones which we really want to handle in this way.
