PC-Phone USB Sync

This app makes content folders the same on your PCs, phones, and removable drives, with an offline-first design that keeps your content private. Compared to other content-management tools, this app offers some crucial advantages:

• Because it updates content folders only for changes, it's quicker and gentler on your drives than full copies in file explorers and other apps.
• Because it uses your local drives to transfer content, it's faster and more private than clouds and other tools that use networks and servers.
• Because it runs on demand, it's less of a drain on your battery and more stable than syncs that run constantly in the background.
• Because it syncs in one direction at a time, it's immune to change conflicts that require extra manual steps in some tools.
• Because it works the same on your phones and PCs, it provides a cross-device solution that single-platform apps cannot.

In practical terms, 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 all its subfolders, 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 (a.k.a. mirror) 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 storage 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
• Mirror your music libraries between phones, PCs, and standalone players by USB
• Ensure that your content copies are valid by verifying them with this app
• Or simply back up your phone or PC content to a removable drive for safekeeping

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

To use this app, tap the install 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, media players, 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 propagate them to other devices with this app whenever you wish. These change propagations (a.k.a. syncs) use your USB ports and removable drive, along with a push/pull model that varies 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 push from the device with changes to your USB drive, and then once to pull from your USB drive on 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 its state further 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.
