What can I fit in 100 MB?

~50 MP3 songs. ~30-50 photos. ~1 minute of HD video. Varies by compression and quality.

Email attachment says '10 MB limit.' Is that 10,000 KB or 10,240 KB?

Marketing standard: 10 MB = 10,000 KB. But file systems may count 1,024 KB per MB, showing ~9.8 MB.

Why is my 100 MB file showing as 95-97 MB on Windows?

Binary vs decimal. 100 MB (decimal) = ~95.37 MiB (binary). Windows uses binary internally for display.

My USB drive shows 'Remaining space: 250,000 KB,' and I'm trying to copy a 250 MB file. Will it fit?

250,000 KB ÷ 1,000 = 250 MB. Your file is exactly the size of your remaining space—it should fit with no room to spare.
