Filen upload errors run out of disk space

[lawmanuk]

Describe the bug
When using filen desktop and uploading many files from usb hdd, it seems to be copying the files to my local ssd and filling up space completely instead of uploading directly. this is causing my ssd to run out of space and files not being uploaded.

To Reproduce

1. mount directory in ssd with filen desktop linux
2. copy 600gb from usb hdd to filen mountpoint (i used freefilesync)
3. it ends up filling up the ssd until it runs out of space, instead of copying directly to filen cloud.

Expected behavior
uploading from usb to filen mountpoint, uploads directly to cloud

System (please complete the following information):

• OS: Sparky linux testing (based on debian testing)

• filesystem and disk type used - ext4 ssd

Additional context
Uploading to filen is a nightmare after attempting for 3-4 weeks now using rclone, desktop mount
