that's not how mega works, mega storing it's downloading file to a system file from the browser system file, and it's stored with a random name, not like how other download worksYou go to C:\Users\"YourUserName"\Downloads. where downloads usually go.
Then you can find the file you want to delete, it should correspond with what the browser had it named when downloading, (Usually a corrupt file wont have a file association with it yet so they are easy to spot)
There is also a Shortcut Ctrl+J to use in Edge to see the exact filename of the downloads and where they are to download too.
i mean, i already download some files in mega and workwhat is mega? some garbage utility you use? nevermind, it's cloud storage, look at the mega documentation
it looks like a pirates heaven--except it doesn't appear to actually work too well. have fun getting infected.
