WHY THIS APP

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 in any direction 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.


USAGE BASICS

All versions of this app are full, free, and ad-free. Get its Android version at the Play store and its Windows, macOS, and Linux versions at quixotely.com. 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 this app too.

To run syncs, this app uses a simple on-demand model to transfer changes between your devices: you'll push changes to your removable drive on one device and pull them from the drive on another. This makes folders on your devices and removable drive the same both quickly and securely. You'll also find tools to roll back sync changes, copy folders in full, and compare content copies.

For detailed information on how to use this app to sync your content, please see the in-app help in the app's Help tab or the online user guide at https://quixotely.com/PC-Phone%20USB%20Sync
