And mostly we formatted the USB with FAT File System because it’s compatible with multiple operating systems. But the FAT file system limits the file size 4GB. There is a difference between Quick Format and Full Format Of USB.

Quick Format: If you Format your USB with quick format option, then it does not erase files from USB. You could recover your deleted files with Data Recovery software. The data or files are in the USB but you can’t see. When you load new files in then these files overwrite on existing files.
