What is the problem you are having with rclone?

I'm not sure if it's a bug, but renaming a file via the web page removes the blake3 hash, while doing so via rclone (with copyto or moveto) keeps it.

What is your rclone version (output from rclone version)

rclone v1.73.0

• os/version: Microsoft Windows 11 Home 23H2 23H2 (64 bit)
• os/kernel: 10.0.22631.6199 (x86_64)
• os/type: windows
• os/arch: amd64
• go/version: go1.25.6
• go/linking: static
• go/tags: cmount

Which OS you are using and how many bits (e.g. Windows 7, 64 bit)

Windows 11 Home 23H2 (64 bit)

Which cloud storage system are you using? (e.g. Google Drive)

Filen

The command you were trying to run (e.g. rclone copy /tmp remote:tmp)

rclone hashsum blake3 filen:test/2.jpg

A log from the command with the -vv flag (e.g. output from rclone -vv copy /tmp remote:tmp)

rclone hashsum blake3 filen:test/2.jpg -vv
