RClone GUI R2 Bucket Mount Copy Progress

What is the problem you are having with rclone?

Hello everyone,

I would like to upload files to Cloudflare R2 using RClone Mount. Currently, when I copy a file to the mounted location, it gets copied instantly. However, the file then uploads in the background. I am interested in achieving a real-time upload experience, similar to when we copy and paste files, and can see a gradual progress bar. This allows us to track the amount of data copied and how much remains to be transferred. The current background process is a bit frustrating as it doesn't provide a clear way to trace the upload progress. Could someone please advise me on how to address this issue?

Thank you.

Run the command 'rclone version' and share the full output of the command.

rclone v1.63.1

  • os/type: windows
  • os/arch: 386
  • go/version: go1.20.6

Nothing like this exist today for rclone mount.

You have to get into details how Windows Explorer, WinFS and rclone mount work and interact together and then try to develop (or find somebody to do this for you) something meeting your requirement. Both WinFS and rclone are luckily open source.

good place to start is to check out:


API which let you collect statistics from running mount.

Some bits are already done:

so you can try to build on top of it.
