What is the maximum possible file size (to the nearest gigabyte) for a file on a FAT32 volume?

• 8GB
• 16GB
• 4GB
• 32GB 

EXPLANATION

The maximum possible size for a file on a FAT32 volume is 4 GB minus 1 byte or 4,294,967,295 (232 − 1) bytes. This limit is a consequence of the file length entry in the directory table and would also affect huge FAT16 partitions with a sufficient sector size.[1] Large video files, DVD images and databases easily exceed this limit.
