WHAT IS SFV32?
SFV stands for Simple File Validator and is just that. The reason why SFV exists is the fact that the best archiver around - RAR - lacks a significant ability, namely the ability to put one CRC per volume in a file which spans over multiple volumes. This is bad news indeed when downloading a file wich resides in 40+ volumes and it unpacks with an error there is no way of telling in wich volume the error is.
SFV has a solution to these little problem quirks or RAR. SFV generates an external crc file containing checksums of the files. If something fails when unpacking, simply use SFV and find out which file(s) have errors and RE-DOWNLOAD ONLY THE FAULTY FILES again — this will save time and effort, because downloading the entire set of archives AGAIN from another source still cannot 100% guarantee flawless transmission. But with a working crc you can keep looking for those good files, and you'll know that the files are genuinely part of the same set.

notes.txt
The .SFV or .SFV2 files found in directories are for d/ling
purposes, it (with SFV32 or WIN-SFV32) gives anyone the
ability to test ANY of the archives (generally RAR) without
requiring all of them.
The SFV program generates a text file with a Checksum for
each file... these checksums can then be used to validate
each individual file - with a simple commandline SFV32 will
either LOG the errors or display the errors on the screen.
************************* IMPORTANT **************************
Recommend usage:
Any group releasing ISOs create a checksum for others
to use in testing, since for most people grabbing an
iso is extremely time consuming, the group should take
some responsibility. The New 1.0 win32 and linux versions
create new .SFV2 checksums, they don't work with old
versions of SFV, but the old checksums *ONLY* work with
the new Win32 version of SFV, the UNIX version is incapable
of testing with the old .SFV files, so there is no way to
keep using them for cross compatibility.
The SFV-XDCC bot will continue to offer crcs in both formats
with the distinction in name, old SFV crcs will have the
.SFV extension, and the new crcs will have a .SFV2 extension
To use the new crc files with the commandline versions, just
simply rename them back to .SFV and use the switch for them.
*************************************************************
The preferred crc name is RELEASE.SFV/.SFV2 where release
is the filename of the rars, e.g Dungeon Keeper Gold is
DKGOLD.RAR so the crc file would be named DKGOLD.SFV, the
simplest way to create this name is to let SFV decide, use
"SFV32 -C -2" when creating the checksum, it will find the
first rar and match the name, when testing the -2 again
applies, so any iso with the .SFV file will be tested with
"SFV32 -T -2" read the manual for other commands and more
detailed info.
Many siteops have agreed to use this program and thousands
of ISO couriers have downloaded the program, so if you
didn't hear of it, or it's great benefit you will. So far,
SFV32 and WIN-SFV32 are the only programs to verify files
on-the-fly meaning without user intervention. Filecrc and
Validate require MANUAL COMPARING of the checksums in the
crc files, this is a totally unacceptable way to test isos
which are generally comprised of 40+ rar files.
If you need a detailed explanation of the features, consult
the manual that comes with the program... get the newest SFV!

- REALLY SHORT MANUAL --------------------------------------------------------
SFV32 without parameters by default tests all files in the specified directory
for help information use "SFV32 -?", this will bring up the following screen:
Usage:
SFV32 [T|C] [-S] [-F "Filename"] ["mask1" "mask2" ...]
T To verify files against checksum table
C To Create a checksum table (default)
Switches:
-S Silent output - stealth mode
-F "Filename" Forces SFV to use a specified filename rather than the
default CRC.TXT
-L Enable logging of bad files
-N "Filename" Forces SFV to use a different log filename rather than
the default SFV.LOG for logging bad files when not in
stealth mode
Note:
Make sure all filenames are within quotationmarks (")
If no files are specified *.* is the default
The logging switches has no effect upon creation of checksumtables
All filenames shall be within quotationmarks ("), all others will be
considered as errors.
Simply specifying -N without using -L will not generate a log.
- EXAMPLE OF USE -------------------------------------------------------------
SFV32
Will create a checksum table of all files in the current
directory and store the result in a file named "CRC.TXT" in
the same dir.
SFV32 -F "C:\BADBOY.TXT"
Will calculate CRC:s of all files in the same dir but put the
result in the file "C:\BADBOY.TXT".
SFV32 -F "C:\BADBOY.TXT" -S T "DUMMYFILE.RAR"
Will use the input list "C:\BADBOY.TXT", and verify the CRC of
DUMMYFILE.RAR against the values in the CRC table this will be
done with all output supressed.
SFV32 "*.TXT" "*.ARJ"
Will create "CRC.TXT" in the same dir, and add the entries of
*.ARJ and *.TXT to that table file.
SFV32 MYFILE.RAR
Error, no quotationsmarks around filename.
SFV32 -L T
Will test all files in who has a checksum in CRC.TXT and write
the names of the bad files into a log named SFV.LOG located in
the current directory.
SFV32 -L -N "C:\CRAPPY.LST" T -F "\ACTUALCRC.TXT"
Will test all files with a checksum entry in the file named
ACTUALCRC.TXT that is located in the root of the default drive.
Also all files failing the check will be entered into an
errorlog C:\CRAPPY.LST.
- WARFTD ---------------------------------------------------------------------
For basic Warftpd upload verification, simply use the program with commandline
shown below:
<program> <commandline>
SFV32.EXE T -S "$f"
If you run vfsys, put CRC.TXT in the Dupe exceptions list.
- PROGRAM ERRORLEVELS --------------------------------------------------------
0: All tested files ok, or program executed without errors
1: Error opening/creating listfile
2: One or more of the tested files failed CRC
3: Error processing one or more files, ie read error, open error etc
4: Help displayed, due to command line error or by request
5: No files processed ?!
6: Unable to create logfile
- CHECKSUM FILE --------------------------------------------------------------
All lines heading off with a semicolon (;) or simply consisting of spaces will
be ignored by the parser.
- AUTHOR NOTES ---------------------------------------------------------------
Any buges etc should be reported to me so I can fix them asap.
Alcatraz can be contacted on the following email adress: alc@cyberdude.com
- WHAT'S NEW -----------------------------------------------------------------
v0.20a - First 32-bit release.
v0.21a - Added logging feature and support for comment within checksum file.
v0.22a - Fixed a stupid bug that made it impossible to change checksum
filename, if ya tried it would change the log filename instead.
