Fat32 vs NTFS

Post by siamandm »

Hi all

i just liked to get some difference between Fat32 and NTFs , and i found this image below
main-qimg-bdc0754f4ad3c9bd2a232d3fc249868f.png
it shows that the max partition for NTFS is 2TB, while the max file size is 16 GB !!! if the partition max size is 2TB how you can store a file size with 16GB?

it shows that max file name 8.3 characters ... I tested on my flash memory which formatted with fat32 it accepted 1234567890 X 17 times the file name became (12345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890)
can someone explain, please

for the fault tolerance, what does auto repair mean?
also, what does compression means?

Regards

That table is not accurate; it appears to be out of date.

The maximum partition size in NTFS depends on the cluster size. In modern systems, the partition size can be much larger than 2 TB. See NTFS on Wikipedia.

MS-DOS only supported file names of type 8.3: 8 characters for the name, 3 characters for the extension. Windows 95 and later support long file names in FAT32, up to 255 characters.

See Analysis of fault tolerance mechanisms in NTFS for how NTFS can automatically "repair" errors.

And compression means that it is possible to reduce the size of folders by transparently compressing and uncompressing them using a method similar to zipping and unzipping files.

Hans

Note that 2TB is equal to about 2,048GB. It can easily hold 16GB.

The table mentions 16 TB, I think Siamand's 16 GB was a typo.

NTFS is newer than FAT32, and it has many advantages, especially for large drives. NTFS supports:
- Larger volume
- Larger files
- More files
- File-level permissions
- Encryption
- Compression

So NTFS is more suitable for the hard disk in a (Windows) computer.
USB sticks generally don't need all those features, so they mostly still use FAT32.

Hans

NTFS
NT File System (NTFS) is the most modern file system. Windows uses NTFS for its system drive and, by default, for most non-removable drives. Compatibility: Works with all versions of Windows, but read-only with Mac by default, and may be read-only by default with some Linux distributions. Other devices—with the exception of Microsoft’s Xbox One—probably won’t support NTFS. Limits: No realistic file-size or partition size limits.
FAT32
File Allocation Table 32 (FAT32) is an older file system that's not as efficient as NTFS and doesn't support as big a feature set, but does offer greater compatibility with other operating systems. Compatibility: Works with all versions of Windows, Mac, Linux, game consoles, and practically anything with a USB port. Limits: 4 GB maximum file size, 8 TB maximum partition size.
