storage space

l keep running out of storage on my lap top and have been using flash drives to free up space. it seems i’m running out of space continuously. today i had 302 MB of space left. after today’s (dec 29) update there was 247 MB left.
is it possible that an update was 55 MB ???!!! seems impossible but that’s what is showing up.

thanks

There are infections that delete data and documents. Others, the free space. Be sure your computer is clean.
Anyway, you could have stored temporary files or any other download that uses that space…
