- Note this is a later version than the previous 37.5 version!
-
- ABOUT
-
- *Tries* to defragment PFS partitions by recopying all fragmented files.
- Will run diskvalid in analyse mode to get a list of the fragmented files.
-
-
- DISCLAIMER
-
- I REJECT ANY RESPONSIBILITIES IF YOU LOOSE YOUR DATA.
-
- * NO WARRANTIES * NO WARRANTIES * NO WARRANTIES * NO WARRANTIES *
-
- So, I hope this is clear now. ;-) Sorry, but I had to do this.
-
- NOTE: THIS IS A BETA VERSION. THE NEW FILENOTE, DATE AND ATTRIBUTE SUPPORT
- HAS NOT BEEN TESTED THOROUGHLY. USE AT YOUR OWN RISK!
-
-
- DISTRIBUTION
-
- PFSDefragTry was Freeware, is Freeware and will always be Freeware. Now
- including source. When you want to continue development see below under
- "FURTHER DEVELOPMENT?".
-
-
- FURTHER DEVELOPMENT?
-
- I have no time to fiddle around with this now. Thus I included the source
- code to allow further developments.
-
- You can freely continue development *non-commercially*. This means this
- and further developments can only ever be released non-commercially as
- freeware.
-
- You can continue developing without noticing me. But then please rename it
- when you release it and keep my name mentioned.
-
- I prefer when you contact me when you want to continue development. Then I
- could hand it over to you for further development officially. This means
- you also take over support for it. ;-) (Its not a lot support queries,
- really.)
-
- Continuing development is easy: AmigaE 3.3 is freeware now. Just download
- and use it. But you may well transfer the source to C if you like.
-
-
- TODO
-
- Some ideas I got from users (well there are actually some;-):
- - preserve protection bits and filenotes. Yes, my copy routine didn't
- care about this at all.
- Easy solution: Just make C:Copy resident and use C:Copy CLONE
- Other solution: Implement the needed stuff in the copy routine of
- PFSDefragTry
- (Stefan Schulz, Arnljot Arntsen)
-
- Ideas of my own:
- - some GUI with progress display and stuff
-
-
- REQUIREMENTS
-
- AmigaOS2.0+
- PFS2/3. It also works on AFS, but I really recommended to update to PFS2/3!
-
-
- USAGE
-
- Usage is simple.
-
- PFSDefragTry DEVICE/A,TEMPDIR,BUFLEN/N
-
- As you can see only one argument is needed. And this is the device you
- want to defragment!
-
- With TEMPDIR you can specify where PFSDefragTry should copy the files
- file by file in order to let PFS defragment them. If you do not
- specify it files will be copied into DEVICE/A:. I recommend pointing
- TEMPDIR to an other partition than the one being defragmented.
-
- TEMPDIR must have enough space to hold the biggest file to defragment. To
- find it out exactly try diskvalid DEVICE/A ANALYSE, look which files have
- been fragmented, and look which one is the largest of them. It is always
- save to just leave as much space in tempdir that the largest file of the
- complete partition will fit into there.
-
- Files will be copied one by one. So one file will be copied. Then deleted.
- Then either renamed to its original name if your tempdir is on the same
- device that should be defragmented or copied back to its original place.
-
- If there is not enough space, you get get AmigaDOS requesters. No extra
- space checking is done! Anyway files that are to big will simply not
- defragmented. Nothing else will happen. But you have to click that
- requesters away.
-
- The more free space you have on the partition to defragment the better the
- chance to get a successful defragmentation. PFSDefragTry ONLY tries do
- use PFS to defragment files. It does not defragment the free space on a
- device.
-
- Note: Currently all files that PFSDefragTry copies to defragment them
- will be set to the actual date! This is due to my own copying routine
- which simply uses AmigaDOS Read() and Write(). C:Copy doesn't like
- filenames with wildcards in it so I could not use it.
-
- Maybe future versions will take care of the date stamps of the files. I
- don't need this, so it may only be implemented when someone ask me to do
- it.
-
- The last parameter specifies the buffer size in bytes the copy routine
- will use! Default value is 65536. I recommend to set this to 1048576
- - 1 MB - or even more in order to avoid unnecessary hard disk head
- movements at least when TEMPDIR is on the same hard disc than the
- partition that is defragmented.
-
- Some words about efficiency: It works fairly good, but it does not always
- be successful. Running it several times will most likely give better
- results than running it once.
-
- When you have question or suggestion don't hesitate to email me.

- HISTORY
-
- Hel = Martin 'Helios' Steigerwald
- Max = Stefano 'Max Headroom' Pucino
- When nothing is stated assume Hel ;-)
-
- revision 1.5
- date: 1999/10/08 18:15:35; author: helios; state: Exp; lines: +37 -25
- - now I have it... hmmm... Stefan stored the pointers to the
- comment, the filedate and the protection bits to variables
- and freed the DosObject afterwards and then used them to
- restore the file data... this can't work or only works
- in the case when the freed structure has not been overwritten
- again
- AH this, sucked ;-)
- hopefully it really copies filenotes now... now keeps
- fib open till not used anymore
- - added some more comments to the source
-
- revision 1.4
- date: 1999/10/08 17:35:31; author: helios; state: Exp; lines: +76 -43
- - cosmetical changes, revised error messages
- - tried to find not setting filenote problem... this
- is strange. I could reproduce it when there was other
- activity on disc but after some changes it seemed to
- be gone
- - cause of that I added all error checking it can get
- when comment can not be set it should really complain
- now
-
- revision 1.3
- date: 1999/09/29 12:23:22; author: helios; state: Exp; lines: +2 -2
- - changed some texts
-
- revision 1.2
- date: 1999/09/29 12:15:27; author: helios; state: Exp; lines: +29 -6
- - now under control of HWGRCS (Hel)
- - implemented CTRL-C check while copying (Max)
- - implemented support for filecomment, date and attributes (Max)
- - This tool is completely Y2K-free ;-)) (Max)
-
- PFSDefragTry 37.4 (17.9.1999)
- - changed name to PFSDefragTry, since PFS3 is out, and it also works
- on AFS
- - changed legal status to public domain
- - added FURTHER DEVELOPMENT?
- - added TODO
- - little other changes in this readme
- - updated my email address!
-
-
- THANKS GO TO
-
- Stefan Pucino for the 37.5 update with filenote, attributes and date
- support that I put into 1.2
-
- Simon Dick for the idea.
-
- Mark Harden for his work on the AFS FAQ and the support Fourth Level
- Developments should have actually done.
-
- Michiel Pelt for PFS2!
-
- Wouter van Oortmerssen for Amiga E
