Howdy all, I have a file called C-1202xx.xxx and when I search for another file called C-975xxx.xxx I get the 1202 file to pop up in the find window along with the 975 files. Long story short, by right clicking then selecting properties I noticed that the DOS filename does not match the Windows filename. How can this be?? How do I modify it so that they match? It's not any real big deal, just more of a curiosity. I am using Win98 TIA!!
Could you post the two file names please? If the windows filename is 8 characters or less and the extension (after the period) is three characters or less, they should be the same.

The windows filename is c-1202-coupler.dwg and the dos name is C-9752~1.dwg. I checked for the sulfnbk.exe and found it in C:/Windows/Command.

DOS only supports up to 8 characters and a 3 character file extension. Example: If yo make a file called 123456789.txt, in dos it will show as 123456~1.txt. If you are using a DOS promt from inside windows, just encase long filenames in quotes like so:
C:\"My Documents"\"My Folder"\myfile.txt
and it should work fine.

I am fully aware of the Dos 8 character situation, unfortunately that's not what I am currently dealing with. To use your example, if I have a file called 123456789.txt, windows displays it correctly, however the DOS name for the file is abcdef~1.txt. Obviously they do not match, yet they are the same file. Why don't they match, and how do I correct the problem? It's not a major issue except it is screwing up file searches because Windows find it both by the DOS name and the Windows name, which I have pointed out are not even close in appearance.

"I am fully aware of the Dos 8 character situation"
If that is true, then you realize that you CAN'T make the 2 filenames match UNLESS the windows one is 2 characters or less. Then they will match.The windows search does not use, abuse or confuse the dos file name. It is strictly useing the LFN.
If your search is finding the wrong file, I would suggest the search criteria is wrong.You are using Find Files?
What criteria are you using?

How or why do you think they are actually the same file?
Did you use DOS to locate both filesnames with the DIR command?
How was each filename created?

Perhaps this picture will explain better that I have. If you look in the far right column you will see the long file names. Take a close look at the C-1202 files. The fifth file called C-1202-COUPLER.DWG does not match the DOS filename in the far left column. As you can see there are a number of C-1202 files that have longer than 8 characters. I noticed that the DOS truncation only goes up to ~4. So does that mean DOS cannot handle ~5 and up in it's truncation? Windows does use the DOS name when you use the "Find Files or Folders". In otherwords, I am able to find the C-1202-COUPLER.DWG by both it's long filename and DOS name. So basically, comapare the DOS and long file names of the C-1202 files. You will see there is a C-1202~1 through C-1202~4 then it seems to make up it's own filname for the remainder of the C-1202 files.

This is it, if this don't work, screw it.

OK. Great screen shots. Your idea about DOS
only going to 4 files does not seem to be
correct. I created text files in notepad and
saved them as follows: 123456one.txt,
123456two.txt, 123456three.txt, etc; I went
all the way to "six" - and all appear with
the same names in DOS and in Windows. They
are, of course, truncated in DOS, but show
up ~1, ~2, ~3, ~4, ~5, ~6.Next, I created text files c-1202-one.txt,
etc; Using the same beginning as your files -
still, works. Dos shows 1-6.I am not going to swim through the MS
knowlegebase, but you may want to.Make backup copies before trying any
renaming. Rename in windows so that there is
some character unique within the first 6. If
you rename in DOS, you would lose the
benefit of long file names - but there is a
website that has programs to work with long
file names in DOS (LFN).You might post this to the DOS forum (link -upper left of page)? Maybe someone there knows why.

If your CAD program itself is looking for filenames as they now exist - my answer is, you are out of luck. You'll have to work with both names.
