Maximum filesize

By yorel ·
I'm running Win98SE. I'm limited to a max filesize of 4Gb. I've been told that Win2000 bypasses this 4Gb barrier. Is this correct?

Maximum filesize

by pschuvie In reply to Maximum filesize

Well if you keep in mind that Windows 2000 is now intended to address /solve scalability and mega enterprise class problems then the basic answer is yes.

NTFS5 is a 64 bit addressable file system and so it certainly will be able to handle much more than the 32 bit system of Win98SE.

As quoted from Microsoft Knowledgebase Q100108

NTFS has greatly increased the size of files and volumes, so that they can now be up to 2^64 bytes (16 exabytes or 18,446,744,073,709,551,616 bytes)

AndLon Collins, Microsoft Support Professional

FAT and HPFS both have internal limits of 4 GB due to the fact that they use 32-bit fields to store file sizes. NTFS uses 64-bit fields for all sizes, permitting its data structures to handle volumes upto 2^64 bytes (16 exabytes or 18,446,744,073,709,551,616 bytes) ? minus a little overhead. 16 exabytes is really, really huge.

This value is the theoretical limit for the NTFS file system. Practical limits having to do with the maximum allowablepartition size described above limit the size of an NTFS partition to approximately 2 terabytes. Because the 32-bit fields of the partition table refer to the number of sectors in the partition, disks with larger sector sizes translate into larger permissible partition sizes. Currently Windows NT supports sector sizes up to 4 Kilobytes. With 4KB sectors, Windows NT can support a 16 terabyte partition. As new hardware or software schemes become available, NTFS will be able to handle substantially larger volume sizes.

However keep in mind that it is not ONLY the file system that controls/limits the actual file size but the Hardware restraints of bios, controllers, and harddrives relating to sectors, clusters and transfers.

Hope that helps
