Currently the most commonly used Linux file systems are ext2, ext3 or ReiserFS. To support files larger than 2 GiB on 32-bit systems, Linux need to use Large File Support (LFS). The LFS support is done by the Linux kernel and the GNU C library i.e. glibc. LFS raises the limit of maximal file size. For 32-bit systems the limit is 2 GiB but using the LFS interface on filesystems that support LFS applications can handle files as large as 2^63 bytes.
