Frequently asked questions
- Why does my 1 TB hard drive show less space in Windows?
- Drive manufacturers label storage in decimal (1 TB = 1,000,000,000,000 bytes), but Windows reports in binary gibibytes. 1 TB decimal is about 931 GiB, which Windows may display as roughly 931 GB.
- What is the difference between GB and GiB?
- GB (gigabyte) in strict SI usage is 10^9 bytes (1,000,000,000). GiB (gibibyte) is 2^30 bytes (1,073,741,824). This tool uses the binary 1024-based definition, consistent with how RAM and OS file systems count memory.
- How many gigabytes is a typical 4K movie?
- A 4K Blu-ray film typically runs 60-100 GB. Streaming versions are compressed to 15-25 GB per film. The exact size depends on codec, runtime, and HDR encoding.
