Hi all guys. Does anybody know if there is any version of defrag suitable to be used with long file names, without destroying them?
Very Thanks.

If there is a possibility of several things going wrong, the one that will cause the most damage will be the one to go wrong.

Is DOS req'd? A commandline version won't work?
Here's a link to the greatest little defragger since hot biscuits and gravy.

It is fast!

You're booting straight to dos and not opening a dos window, right? When booting to dos on a 9X PC you don't have LFN support. So, does your dos 7.1 even allow long file names? Do a DIR and check. If not I doubt you need a special defrag.

But, given that, you might look at NTFS4DOS. It has a defrag utility--DFRGNTFS--that does preserve long file names and I believe it can also be used on FAT drives. And it does run from dos but only after the NTFS4DOS files load. I've never tried to run it in any other context. But you could try it and see what happens.

I think there are several files named dfrgntfs.exe. One is an MS file for NTFS drives. Another is from a utility called 'diskeeper'. The one ntfs4dos uses may be one of those or another one entirely. To be sure you can find a download for ntfs4dos, run it and then copy dfrgntfs.exe to your 7.1 machine.

Banfield you are using the Weigner "illegal" CDU-DOS 7.10 I presume ??

Therefore you need to install Windows 98SE and use the MS-DOS SubSytem from that, this would allow you to pop back into Windows to Defrag.

Alternatively you could look into the Defrag in FreeDOS, to see if it is LFN compatable !!!

"Banfield you are using the Weigner "illegal" CDU-DOS 7.10 I presume ??"
I don´t know if it is legal, or not. I only know it is unofficial. It is called MSDOS 7.10, and come in 2 installable floppies from an ISO image. It is sayed that it is the true DOS running background in w9X.
I´d installed it into my 5 80486´s, (one of them is a recently buyed TI TravelMate 4000 486 DX2) and it is running fine and stable, but I wanted to know how to defragment the HD without breaking LFN´s. I hate windows, and use it so less as possible.
Thanks for the links. I´ll try them.
Best regards.

If this is win98 dos then you probably don't have LFN support anyway. But again, just do a DIR and see if the long file names show or if you get the truncated 8.3 form with the ~1.

Dave: I can see he two formas of dir and file names, with the tilde and complete. But it isn´t the matter. I added the sentence in autoexec.bat

setdir /o /p

and I can see both forms of directories or file names, ordered in a page per screen and in alfabetic order.
But, I want to reorganize the disk, like defrag did with the 6.22 and all other previous versions.
No mothe simple that it.
Very Thanks.

I found this:

http://ms-dos7.hit.bg/doskbc3.htm

DEFRAGD.EXE works on fat16 drives only but protects long file names. DEFRAGW.EXE works on fat32 drives and protects long file names but must be run from win 3.1x. The defragw link on that page is dead. I couldn't find a live link except for a defragw associated with PCmesh and I think that is just a windows utility.

DAVEINCAPS, a long time ago I went looking for that particular defragw.exe and I found it at http://newdos.yginfo.net/dosware/ site by Gozillia leaching that page (back when it wasn't dead). For some reason the link did not connect to it but I downloaded and examined it anyway to find this result with a binary file compare against ME's defrag.

Comparing files defragw.exe and defrag.exe
000000BF: 03 04

I did try it in Win98 with the mod shown, it worked fine. Don't know what to think. My archived copy has a download date of 9/24/05.
Defragd.exe has a 4 minute difference from the other file. I don't have GoZillia installed to check if there are hidden executables avilable from the page you posted but I did download defragd.exe from it just fine - amazing after all this time. FC: no differences encountered just in case anyone was wondering.

I guess that's the 'small change' the link mentions between 98/ME defrag and defragw.

Unfortunately there's not much call anymore for pure dos utilities so I can't see anyone writing a defrag with fat32 and LFN support.

I still wonder about dfrgntfs--at least the one with NTFS4DOS. If I get around to it I'll do a 98 install and then try it.

melee5,

I have been looking for a defrag utility like the DEFRAWG you mention, for quite a long time. Would it be much difficult for you to e-mail me that defragw.exe you downloaded back in 2005? (OK, I know this is a DOS forum and that I am asking for a defragw.exe that works in Windows, but I will also download and use the DOS-only defragd.exe, since my Win 3.11 system is built on top of Weinger's MS-DOS 7.10). Thanks everybody, this discussion and information was much useful!
