NTFS question

[Jeff7181]

Is NTFS a 32-bit file system?

What has 32bit or 64bit got to do with the file system? 😕

NTFS is a file system. Period.

You can use it with both 32 and 64 bit processors.

Who said anything about processors?

I'm talking capacity.

*EDIT* For example... FAT16 is a 16-bit file system
2^16 x 32KB (max cluster size) = 2,097,152 KB = ~2 GB... hence the 2 GB partition size limit of FAT16

**EDIT** FAT32 is a 32-bit file system
2^32 x 32 KB = 137,438,953,472 KB = ~ 137 TB

I think I also just found the answer to my question... I believe in it's current implimentation, the max cluster size is 64 KB for NTFS, and the max capacity per volume is listed in many places as 256 TB
2^32 x 64 KB = 274,877,906,944 = ~274 TB which is pretty close to the listed spec of 256 TB

... but that begs the question, how do they come up with the theoretical maximum of 16 EB for NTFS?

64bit internally.

2^64 clusters....2^64 x 64KB.

From the above link:

NTFS Size Limits

Maximum file size
Architecturally: 16 exabytes minus 1 KB (264 bytes minus 1 KB)
Implementation: 16 terabytes minus 64 KB (244 bytes minus 64 KB)

Maximum volume size
Architecturally: 264 clusters minus 1 cluster
Implementation: 256 terabytes minus 64 KB ( 232 clusters minus 1 cluster)

Files per volume
4,294,967,295 (232 minus 1 file)
