ELI5: Why can FAT32 only store files smaller than 4 GB?
gpt
The file allocation table, the FAT, is record-keeping, like paperwork for tracking what files are stored where on the disk and how big they are.

The spaces in the form that it has for file size on the paperwork, are only large enough to hold numbers that represent a maximum of 4GB. 32 bits, 32 spaces.
