The question of export folder in h5p

Respected,

can i delete files in uploads/h5p/exports? The export folder is very large and I need a lot of time when I back up the site.
If I delete files in the export folder, will I be able to retrieve h5p interactivity on the Reuse button again?

 

Wordpress version 5.7.1.
H5P version 1.15.0.
