Some video download programs will create duplicates on PCs and laptops, where there is one file "downloaded" but then duplicates and other partial files created on the same device. Does SurFast Video Downloader do that?

Are there any video tutorials on how it works and creates files for download?
Also, how would a user delete or clean up their device after downloading several files?

Hello Boltaire001, no, we did not do that. However, I need to mention that if you use the Tracking - auto download, the removed videos will be downloaded again. I guess this is not your case.
You can purchase a license to test it. You can get a refund if you are not satisfied.
