I’m using rclone with a remote configured to Dropbox and I mount it on Windows

I’m using rclone with a remote configured to Dropbox and I mount it on Windows with the following command:

mount DropBox: X: --config "C:\Users\Soporte\AppData\Roaming\rclone\rclone.conf" --vfs-cache-mode writes --vfs-cache-max-size 50G --log-file=C:\Rclone\rclone_mount.log --rc --rc-addr=localhost:5572 --rc-no-auth --rc-web-gui

If I copy a folder of around +50GB directly to the X: drive:

  • Does rclone upload the files to Dropbox immediately, or does it first keep them in a local cache and then sync them?

  • If the PC restarts or shuts down before the upload is complete, what happens to those files? Do they get lost, or do incomplete files remain in Dropbox?

  • What upload speed should I expect when transferring large files to Dropbox through rclone mount, and is there a way to monitor the upload speed/progress while the transfer is happening?

welcome to the forum,

  1. the file is copied to local cache.
  2. the file is uploaded from local cache to cloud.

run rclone mount again, and rclone will re-upload the entire file.
else the files are lost in the vfs file cache.
it is possible for incomplete files can remain in dropbox.

often rclone will upload the file with suffix .partial, then rename it once upload is complete.


that mostly depends on your internet connection.
do some simple testing and then you know.
