Hi BrendaHog,
Welcome to the Sony Community!
The imported files showing up on PlayMemories Home are also saved in the default picture folder of your computer. If you want to organize the files and save them in separate folders, open the default folder (My Pictures in Windows, Gallery in Mac) and cut and paste the files to the new folder you want to save it into. After doing so, open PMH and click on the Files tab. Select Add folders and mark the new folders where the pictures are to view/edit them in the software.
In future, if you want to import the pictures to different folders, create or change the file destination in the PlayMemories Import page. To know more about how to use the program, please click here.
