What does it suggest when it say 3% of 2.0 GB expect on my computer?

What does it suggest when it say 3% of 2.0 GB expect on my computer?

Depends. It could suggest 3% free space left (which is not a lot) or 3% used (which is profoundly of free space left).
are you talking disk or memory?
3% is around 60 megabytes

1 KiloByte(KB) = 1,000 bytes

1 MegaByte(MB) = 1,000 KB

1 GigaByte(GB) = 1,000 MB

so it talking more or less 60 MB out of 2,000 MB

So if says free consequently 60 MB is all you hold left

If it say used the you have 1,940 MB gone
