I wish to use Freefile-sync(An interactive GUI sync) to use with Rclone mounted folders. But freefilesync cannot read folders mounted by Rclone.
Kindly guide me on this issue.
This feels like a bad idea. Or at least a risky one. What are you trying to accomplish? If it's one-way sync, just use rclone directly. If it is two-way, check the wiki for at least 4 wrappers to do two-way. (disclaimer: I wrote two of them but they are all different with their own pros and cons).
But if you are really set on doing this, you need to provide a lot more information! There is absolutely nothing to go on in your post and there could be any number of issues standing in your way.
