The downloading functionality is perfectly successful and works excellently. However, the system generates multiple identical files with the same names, making it impossible to know which one I should actually download.

This is extremely frustrating, and the issue still hasn't been resolved. Please fix this problem. While there are no issues with the actual downloading process, I cannot distinguish between files when I try to download a video.

The file organization is very confusing:
1. The thumbnails or preview images are identical.
2. The filenames are exactly the same as the original file I'm trying to download.
3. It is unclear which file is which.

This is a major issue. Please address this and fix it as soon as possible.
