There is no shortage of apps to backup contacts, photos, calendar, videos, etc from Android to PC.

I am looking for one (gratis) that allows me access to the full file system - in both directions.

Beyond that, I don't care e.g whether it uses USB cable, WiFi, BlueTooth. A slight bonus might be searching for file name/contents, but I can achieve that with other tools, so it is just a convenience, not a requirement.

    Full file system access requires a rooted Android device. Is your Android device rooted?

  • Yes, it is. Technically, I don't require the full file system, just more than the standard contacts, emails, photo, video, music, etc which most apps offer.

    Contacts and Emails you won't find in the file system. Further, talking of bi-directional: as long as it's just "your documents", I see no issue – but as soon as it goes beyond that: I doubt that Windows understand the Unix file permissions, so after sycning back those might need to be adjusted (to what, and how should the sync tool know?). That said: did you take a look at my corresponding app listing? Synchronizing Files and Folders – the SMB-section would be the one you're most interested in.

When I want to transfer files from my Android phone and USB is acting up, I use Cx File Explorer, which has a feature to open an FTP server which you can then access from your desktop.
