If you want to remove your account on Mediafire, a website that’s specialized in file sharing and storage, you’ll see in this manual that you can easily do that in the settings of your account.
I’ll show you below some pictures on how I managed to delete my profile step by step using a desktop computer:
1 Go to https://mega.co.nz and sign in to your account
2 Click on your name in the upper left corner
and select Account settings.
3 Look for the Edit button next to Account details
4 You’ll find now on top of the page a Delete my account button
5 Enter your password to remove your account
You’ll see a confirmation that your account has been deleted.
