- What's new?
- -----------
-
- 4 August 1998, changes for version 0.85:
-
- - Requesters which ask for a SFS disk to be inserted will now be
- retried automatically when a disk is actually inserted.
-
- - SFS now guarantees data is commited atleast every 20 seconds,
- even if the disk is being accessed continuously.
-
- - BUGFIX: The filesystem no longer gets confused when it thinks a
- disk is inserted twice. This fixes problems with
- omniscsi.device.
-
- - BUGFIX: Renaming a file to an empty name with the workbench now
- returns 'object name invalid' instead of 'object not found'.
-
- - BUGFIX: Creating a dir with the same name as a file no longer
- deletes the file.
-
- - BUGFIX: 100 character limit is now enforced, instead of allowing
- you to create names of any length.
-
- - Copyback mode added to internal caching system. This helps a lot
- to speed up small write operations. I also tweaked the cache
- system a bit for performance.
-
- - BUGFIX: Creating files larger than 32 MB using SetFileSize()
- now works correctly. This fixes a problem with creating large
- file disks using Shapeshifter.
-
- - BUGFIX: Write protection status is now checked each time a disk
- is inserted, not just at startup.
-
- - BUGFIX: Reading directories has been made a bit more robust which
- will fix problems with some programs.
-
- - Error messages returned by SFS when there was an error accessing
- the device are improved.
-
- - Included SFScheck in the archive -- this is a program to check
- the structure of your SFS disk. It will report any errors it
- finds but won't make any modifications. Read its docs and use
- it reguraly if you value your data!
-
- Note: This version is compatible with the previous releases of SFS
- starting from version 0.67. There is no need to reformat
- existing SFS partitions.
-
-
- 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.

- 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).
