Large File Support
GDAL supports reading and writing large files (> 2GiB) if it is possible in your operating system. Notes about large file support on Linux available here: http://www.suse.de/~aj/linux_lfs.html . In short: if you have kernel 2.4.x and glibc 2.2.x you are in luck. Maximum file size depends on cluster size. For ext2 filesystem with 1 KiB clusters it is 16448 MiB, for ext2 with 4 KiB clusters it is 2048 GiB. Other filesystems can handle even larger files.
Information about large file support in Windows could be obtained at MSDN. In short, maximum file size at NTFS is limited by (264 - 1) bytes, at FAT32 and FAT16 it is (232 - 1) bytes. So don't try create files larger than 4 GiB on FAT32. In some cases you will not get an error message during jumping over 4GiB barrier, but all your data will be lost. This is not a GDAL bug, this is Windows problem.
