When we transfer photos or videos, wechoose MultiSelect-Select all --- Copy To,but the Selected quantity is 499 for idiskk max and 1000 for iPhone, only partial photos andvideos are transferred.
In order to display better and not take up toomuch memory, we set up an internal storageone-time display 1000 pcs, external one-timedisplay 499 pcs. When we do transfer or deletion, only for the displayed items. Thephotos or videos not displayed would not beprocessed. We suggest to use the One-Click Backup function if there are lots of pictures need to transfer. All the photos would be shownonce Backup finished.
