The Be File System (BFS) or loading file system is a 64 bit - journaling file system , which the company Be Incorporated for the operating system BeOS was developed. It can manage data volumes with a size of up to 2 EiB ( Exbibyte , 2 60 bytes); the speed of the file system is independent of the size of the managed data. This was achieved through a database- like management of the file system. It supports metadata and associative file management . The maximum length of file names is 255 characters.
BFS is used in the further development of BeOS, the ZETA operating system, which had to be discontinued in the meantime. The open source operating system Haiku , based on BeOS, offers a reimplementation of BFS with OpenBFS , which is also provided by Syllable and used in a modified form by SkyOS . Linux includes its own driver for this file system.
