DTP uses too much disc space

[StephenL]

It temporarily uses that space but iCloud should delete those files eventually.

According to support try: Option key , right-click the sync location and choose Verify Location Thoroughly . That worked for me when I noticed the same.

iCloud Sync Bug or Not?

This is controlled by iCloud, not us. Do note, it’s not wise to delete resources like this manually. I suggest you hold the Option key, right-click the sync location and choose Verify Location Thoroughly.
