How to Transfer Files (Step-by-Step)

  1. Connect to the same network: Ensure both your mobile phone and your PC are connected to the same WiFi router. Alternatively, you can turn on your mobile's Hotspot and connect your PC to it.
  2. Start the Server: Open the BSR FTP Server app on your Android device and tap the big "Start Server" button.
  3. Get your FTP URL: The app will display a local address on your screen. It will look something like this:
    ftp://192.168.1.5:2221
  4. Open PC File Explorer: Go to your computer and open "This PC" (or Windows Explorer). Click on the top address bar, type the exact FTP URL shown on your mobile app, and hit Enter.
  5. Manage your files: Done! You will now see all your mobile folders. You can freely copy, paste, rename, or delete files directly from your PC.

Frequently Asked Questions

Does this consume my mobile internet data?
No! The transfer happens completely locally over the WiFi router or Hotspot signal. It does not use your active internet data plan.
Is this secure? Can anyone access my files?
The FTP server is only active when you tap 'Start', and it can only be accessed by devices connected to your exact same WiFi network. Once you click 'Stop', access is completely disabled.
Does this work on Mac or Linux?
Yes. FTP is a universal protocol. On Mac, you can press Cmd+K in Finder and enter the FTP URL. On Linux, you can enter it in your default file manager's network tab.

⚠️ Known Limitations

  • SD Card (External Storage) writing might be restricted on newer Android versions due to Google's Scoped Storage policies.
  • Transfer speeds depend entirely on your WiFi router's bandwidth capacity (5GHz routers will transfer files much faster than 2.4GHz routers).
  • The app must remain open in the background to keep the FTP server alive during large file transfers.
