What is the size limit for FAT32?
The maximum file size supported by FAT32 is just under 4 GB. If you need a cross-compatible file system that supports larger files, exFAT is the way to go. In fact, with exFAT, the file size limit is just under 16 EB (Exbibyte) or 1.845e+7 TB.
How big is the FAT table?
The FAT 16 system uses 32 sectors of 512 bytes each to store the root directory. This limits the size of the root directory on a hard disk to 512 entries. In other words, you can have at most 512 files and folders in the root directory.
How do you calculate FAT table size?
Consider a disk size is 32 MB and the block size is 1 KB. Calculate the size of FAT16. Now, I know that to calculate it, we would multiply the number of bits per entry with the number of blocks. So first step would be to calculate the number of blocks = (32MB)/(1KB) = 2^15 = 32 KB blocks.
What is large FAT32?
If you do need those larger file sizes, you’ll need to stick with something like NTFS or exFAT. The advantage to using FAT32 is portability. The truth is that FAT32 has a theoretical volume size limit of 16 TB, with a current practical limit of about 8 TB—plenty for most USB drives.

What’s the difference between FAT32 and FAT16 directory table?
Basically, there is only one difference between the Directory Table of FAT16 and FAT32. The Difference is: the Reserved OS/2 Byte (Offset 20 [14h]) in the Short Filename Structure is replaced with the High Word of the Cluster Number (since it’s now 4 bytes instead of 2).
Why is FAT32 not a journaling file system?
FAT32 is not a journaling file system, which means that file system corruption can happen much more easily. With NTFS, changes are logged to a “journal” on the drive before they’re actually made. If the computer suffers power failure during file writing process, the system won’t need a long scandisk operation to recover.
