When trying to copy a large file to an MS -DOS formatted drive there seems to be a 4 GB limit to the allowable file size. Is there a way of overcoming this limit. or does anyone have a work around, other than breaking up the file into smaller chunks. Thanks

The 4GB is a limit of FAT-32, and is not present in NTFS. Unfortunately, I do not believe you can mount and write NTFS on OS X. So, the only option I can think of is reformatting the disk to NTFS, mounting it on a Windows machine, and then doing things over a network.

Stuffit Deluxe 9 has a feature to split an archive across multiple segment sizes of your choice. I have been very happy with this program. I was surprised FAT32 allows up to 4GB files. I would have thought it would be limited to 2GB files. I have forced all my PCs to use the Mac filesystem by installing a Addon program that allows Windows to read Mac filesystems.

FAT32, as the name would indicate, uses (unsigned) 32 bit data structures to point to data. 2^32 ~= 4 GB.
