Windows data files copy limit exposed

Is there a limit how many files you can copy in one step? And if so, where is this limit? A post in the forums of a popular hardware site provides more clues where this limit may be and which hardware is affected.

We found this information earlier this week in a post on Ace’s Hardware where a user reported his findings. Hirschma writes that he was unable to copy large numbers of files under certain Windows/hardware environments and was confronted with an error 1450, causing an instability and requiring a system reboot. Depending on the Windows versions, he discovered varying limits: 760,000 in Windows XP 32-bit and about 2.7 million in Server 2003.

But there is a spicy twist to the story: Systems equipped with AMD Athlon Socket 940 (nForce3 chipset) and Socket 939 (Nvidia chipset) processors were passing the tests with flying colors, while machines using an Intel Core 2 Quad Q6600 or Intel Xeon 3070 processors failed at 760.000 files. A Server 2003R3, Xeon-based system failed at 2.72 million files.

Since hirschma’s 32-bit attempts on Intel failed, we felt there was enough reason to contact both Intel and Microsoft to find out whether this is a know issue, if it is considered to be an issue and whether a patch is in the works.
