i vs zDrivePro

This APP can connect to a USB drive via a wired connection and manage the files on it. You can back up photo album files to the USB drive and restore them to the photo album, or back up contacts to the USB drive and restore them. Backup can be done without network access;

zDrivePro is designed to let you use your iPhone like a portable hard drive in your pocket: files reside in the app's own space; from here they are listed, previewed, and managed. WHAT IT DOES? • Drag and drop files from your Mac to the zDrivePro space in Finder → Device → Files tab when connected via USB or Wi-Fi. • Import photos and videos from the gallery with "Add from Gallery"; import suitable files back to your gallery with "Save to Photos". • Full-screen gallery for photos and videos; quick preview for other files. • Share and delete files; list or grid view, sort by name/type/date/size. • Lock with optional Face ID / Touch ID or app passcode — authenticate when unlocking after exiting the app. STORAGE SUMMARY See in-app usage, free space on the device, total number of files, and distribution by type all in one screen. IMPORTANT Deleting zDrivePro from your iPhone will permanently delete all files within the app. Regularly copy important data to your Mac or a trusted backup.
