Theoretically PCGUIDE says virtually no limit due to extensions. As a general rule 4GB was initially the max, but each service pack and upgrade has increased that to some degree. Now with NTFS5 (Windows 2000/XP) There is talk of new systems with hundreds of terabytes. I still believe there is a practical limit as each cluster is only so many bytes ~4KB, and the you have up to 36 bits on an Pentium CPU to address them. 2^36 * 4KB = 2^48 bytes. every 2^10 bytes increases by 1K. so 10 * 4 = 40 ~ 1000: 1,000,000: 1,000,000,000: 1,000,000,000,000 Bytes then 2^8=256 or roughly 256 Trillion Bytes. 1,099,511,627,776 = 2^40 = 1 Terabyte. So somewhere around 256 Terabytes. The good news is with SATA and new RAID configurations, It will be a short time when this is a REAL value for a high end server.

Maximum file size 16 terabytes minus 64 KB (244 minus 64 KB) http://technet2.microsoft.com/WindowsVista/en/library/5025760b-0433-4ba1-a2f4-9338915fdb4b1033.mspx?mfr=true
