Info on the Linux filesystem

Can anyone explain this filesystem to me? I know close to nothing about it, but I do use Linux...

Also, what are the main differences between the Linux filesystem and FAT32/NTFS?
 
Best I can tell you is it is ext2, don't recall offhand the default block size or other specifications, but being the typical "need to know it all" I will look it up my.😀

Besides ext2fs Linux can use may more file systems. Early Linux systems had minixfs (as you know, Linus started working on Linux because he didn't like Minix), then extfs (with 2.2 kernels offically dead) and now ext2fs. The future has may more "native" file systems: SGI's XFS, IBM's AFS, ReiserFS and even ext3fs.

 
Well, ext2 is fairly complex, as is any files system, but I can give you a quick over view. For one, it uses a tree-like structure as oppose to a table like structure that FAT uses. This means finding things on the disk can be done faster as searches on a tree are quicker then searches on a strict table. Because of it's tree-like nature there is also no need for "Defragmenting". ext2 can also be formatted to use 1k,2k,or 4k blocks depending on if you want speed or optimized space. 4k blocks means there are less blocks to search so it goes faster when looking for data, 1k blocks mean there is less wasted space if you have a lot of little files. Hope that helps. Btw, anyone used any Journaling fs' like ext3, jfs, xfs, or RieserFS? I am curious as to which one works best.... I am not even sure if ext3 is usuable yet.
 
I don't know about "far superior". I know it is more efficient then FAT32 is however I am uncertain how NTFS aligns data on the hard disk. NTFS appears to be a table orriented file system like FAT32 (since the conversion between the two is so damn easy) so I would assume that ext2 would be more efficient then NTFS. I have heard NTFS is journaling however, which opens up a hole nother can of worms. Journaling file systems don't suffer data corruption or loss if the system has a power failure or otherwise shuts down in the middle of operation. That is why ext3 (ext2 + journaling), xfs (SGI's Irix journaling fs), jfs ("journaling file system&quot😉, and Rieserfs (another popular journaling fs) are all planned to have linux kernel support.
