PC-Phone USB Sync

This app makes content folders the same on your PCs, phones, and removable drives. Compared to other tools, it's:

• Much quicker than full copies, because it updates content folders only for changes
• Faster and more secure than clouds, because it uses your local drives instead of networks and remote servers
• A cross-device solution for your content, because it runs the same on your phones, tablets, and PCs

This app brings PC-level tools to all your devices. The content it manages isn't just contacts, calendars, and a few stray photos. It's an entire folder of your choice, including its subfolders, and all the photos, documents, music, and other media you value.

By using this app with a removable drive, you can both back up this content on your phone or PC to save it, and sync it between your devices to make it match: from PC to phone, from phone to PC, and any other way you find useful. Among its roles, this lets you:

• Use your phone as a backup device on which you can view and modify saved content
• Switch your content-creation tasks to a different PC or phone with a fast sync
• Sync your camera's new photos to your PC or phone over a direct USB connection
• Or simply back up your phone or PC content to a removable drive for safekeeping

In tech terms, this app's syncs are on-demand and one-way at a time; this keeps you in control, and avoids lossy conflicts. They can also be run in any direction and modify just the items you've changed; this makes them flexible, and faster and gentler on your drives than simple copies.

Perhaps best of all, this app uses your USB ports and removable drives for its backups and syncs, to avoid both slow networks and the privacy perils of clouds. With this app, your stuff remains your stuff, not someone else's point of control.

To use this app, tap the links below to fetch it for your phones and PCs. For most roles, you'll also need a removable drive to store and transfer content. An SSD or thumb drive attached by USB is common, but microSD cards, cameras, and other devices work in the app too.

When using this app, you'll first collect your content files in a folder using a file explorer or other tool, and copy it to your devices with this app's COPY. Use subfolders to organize your content as desired: everything in your folder will be synced in full.

After the initial copies, you'll make changes on one device at a time, and push them to other devices with this app whenever you wish. Change propagations (a.k.a. syncs) use your USB ports and removable drive, and vary by usage mode:

• To back up your content on phones or PCs, you'll run this app's SYNC once: to push changes from your device to USB. This leaves a mirror image of your content folder on your USB drive.
• To sync your content between a phone and PC, you'll run this app's SYNC twice: to push changes to USB on the source, and then to pull changes from USB on the destination. This leaves a mirror image of your content folder on your phone, PC, and USB drive.
• To sync your content between many devices, you'll run the app's SYNC N times for N devices: once to sync from the device with changes to your USB drive, and then once to sync from your USB drive to each of your other devices. This leaves a mirror image of your content folder on all your devices, as well as your USB drive.

In all modes, this app supports automatic rollbacks (i.e., undos) for all the changes its syncs make on each device. This helps ensure the safety of your content. You can even undo multiple syncs to reset your content to a prior state in the past.

To run the app, you'll simply select FROM and TO content folders on your devices; start a SYNC or other action by tapping its button in the Main tab; and monitor the action's progress or inspect its results in the Logs tab or summary popups.

Also in the app, you'll find configuration options, help resources, portability utilities, and tools for verifying the content copies you'll create on all your devices. It's a complete content-management solution.
