Is it safe to delete this project files?

Hello, after a work done we are sending files to a cold file storage and some files inside D5 projects really occupies much space then needed I think. So are the folder directories I given below safe to delete after a work done? If we need to use same file after a month after deletion these file will our project run fine? Thanks.

d5ProjectDirectory/BackUp
d5ProjectDirectory/VideoScreenShot
d5ProjectDirectory/assets/ThumbnailImage
d5ProjectDirectory/SceneImage
d5ProjectDirectory/bg.png

These looks like a temp or cache files but I wanted to ask before delete.

Thanks…

Hi, no, please do not delete them, as they are part of the project file. Those you posted are mainly thumbnails of scenes, objects, and video clips. Unless you really need to clear the space, then you can delete them manually. Besides, if you delete the BackUp folder, then the autosaved version history will no longer work, please notice that.
