Why is Joplin Portable tmp folder so big?

Operating system

Windows

Joplin version

2.14.20

Desktop version info

portable

What issue do you have?

I installed Joplin portable to a D drive that had 80gb free and is surprisingly now full. I have 18k individual notes. Joplin added 2 folders. A folder called joplinPortable\Data\resources is 39GB and a folder JoplinPortable\Data \TMP is 30GB.The tmp folder is almost same size as the resources folder. Does that make sense? Should I have such large tmp folder?

That might be a bug - could you check what files are inside please?
