Hello Jimal. When you download videos from YouTube Premium on your PC, they are saved in a specific folder within the YouTube app. The location of this folder can vary depending on the operating system and the version of the YouTube app you are using.
On Windows 10, the downloaded videos are typically stored in the “Videos” folder in your user account’s directory. To access the folder, open File Explorer and navigate to “C:\Users[your username]\Videos\YouTube”. You should see a list of the videos you have downloaded from YouTube Premium.
On macOS, the downloaded videos are stored in the “Movies” folder in your user account’s directory. To locate the folder, open Finder and navigate to “Macintosh HD/Users/[your username]/Movies/YouTube”. You should see a list of the videos you have downloaded from YouTube Premium.
