Short: Smart Filesystem 3rd BETA version Author: hjohn@xs4all.nl Uploader: hjohn@xs4all.nl Version: 0.71 Type: disk/misc ------------------------------------------------------------ This filesystem is BETA -- this means it is not finished and may potentially destroy all your data. USE AT YOUR OWN RISK! For more information, see http://www.xs4all.nl/~hjohn/SFS ------------------------------------------------------------ What's new? ----------- 14 June 1998, changes for version 0.71: - BUGFIX: It was possible to open a directory as a file using MODE_READWRITE. - NEW: Soft links are now supported. You need to specify a full path with Makelink when creating soft links. Hard links are not supported. - NEW: A new program, SFSformat, is now included in the archive. Using this format command you can quick format a SFS disk and specify if you want case sensitive file and directory names. Note: This version is compatible with the 0.67 and the 0.68 versions. There is no need to reformat existing SFS partitions. 12 June 1998, changes for version 0.68: - BUGFIX: When using a Mask value which didn't end with a 'F' (like 0x7FFFFFFE for example) then SFS would sometimes damage the data it writes to a file. The problem occured for example when unpacking a LZX archive to a SFS disk. 1 June 1998, changes for version 0.67: - First BETA release. Introduction ------------ Smart Filesystem is a new filesystem for your Amiga. A filesystem's main purpose is to store files on a disk in such a way that they can be located and used quickly. How this is done is up to the filesystem. The way information is stored on your disk has a large impact on speed and space efficiency, and so these factors can vary a lot from filesystem to filesystem. Smart Filesystem was created to provide you with an alternative to the Fast Fileystem. Smart Filesystem makes more efficient use of your disk space, has better performance in most areas and will allow for new features never seen before in an Amiga filesystem. Features -------- o Fast reading of directories. o Fast seeking, even in extremely large files. o Blocksizes of 512 bytes up to 32768 bytes (32 kB) are supported. o Supports large partitions. The limit is about 2000 GB, but it can be more depending on the blocksize. o Support for partitions larger than 4 GB or located (partially) beyond the 4 GB barrier on your drive. There is support for the New Style Devices which support 64 bit access, the 64-bit trackdisk commands and SCSI direct. o The length of file and directory names can be 100 characters. o The size of a file is limited to slightly less than 2 GB. o Modifying data on your disk is very safe. Even if your system is resetted, crashes or suffers from powerloss your disk will not be corrupted and will not require long validation procedures before you will be able to use it again. In the worst case you will only lose the last few modifications made to the disk. o There is a built-in configurable read-ahead cache system which tries to speed up small disk accesses. This cache has as a primary purpose to speed up directory reading but also works very well to speed up files read by applications which use small buffers. o Disk space is used very efficiently. o Supports Notification and Examine All. o Supports Soft links (hard links are not supported for now). o Using the SFSformat command you can format your SFS partition with case sensitive or case insensitive file and directory names. Default is case insensitive (like FFS).
