Quick Sync is a free utility program developed by I-O DATA DEVICE INC. for Android devices. It enables users to transfer photos and video files from specified folders on their Android devices to compatible devices like Wi-Fi storage "Pokédra" WFS-SR01/WFS-SR02/WFS-SR03 or Pocket Router WN-G300SR. The program also allows users to manage files and folders on their SD cards, USB storage, or device storage.

One of the most significant features of Quick Sync is its background processing capability, allowing users to continue working on other tasks while transferring files. The program also offers a preview function to view photos, videos, music, and document files on SD cards, USB storage, and device storage. Additionally, Quick Sync saves reduced image files, enabling users to access them even when there is no connection to a compatible device.

Quick Sync is compatible with smartphones and tablets running Android 5 to 12. Users can also change the settings of Wi-Fi storage "Pokédra" WFS-SR series and update its firmware using Quick Sync. However, it is not compatible with WN-G300SR's setting change.

Overall, Quick Sync is an efficient utility program that simplifies file and folder management on Android devices.
