Possible. However most well designed/written apps will do the necessary housecleaning to remove temp files. Or doing so may be an option within the software product.
Could also be some interim backup process that executes automatically and save the work to some default location or user configured location.
Locations being other folders or drives.
What video editing program or programs are you using? What file extensions are on the temp files?
Normally .tmp but some apps use other extensions in order to identify their own files of any type.
Identifying/posting the video editing software product will be helpful.
