This is very weird.
The fact that other programs (explorer, word, excel) see the long filenames points to Quark as the culprit for this behaviour.
However, if Quark can open long filenames on other servers, this would suggest that the problem is a server configuration issue. Try to find out from your system administrator how this server is different from other servers. This should point you in the direction of a solution.
I have checked the quarkxpress support website and only found a problem in v 3.32, which should be solved in 4.1. (see below) Have you by any chance upgraded from quark 3.x to 4.x ? Maybe not all 3.x components were replaced correctly ? Just guessing, but maybe a clean 4.x install woudl help ?
I also found another article with similar symptoms related to photoshop. (see below) It's probably not relavant for you, but I just included it because the author mentions a workaround that does allow him to see the long names: dragging the files to photoshop instead of double clicking them.
Good Luck !
<b>QuarkXPress 3.32r3 does not support long file names under NT 4.0</b>
3764
XPress
Problem:
If you type more than 8 characters when you save page as EPS in QuarkXPress 3.32r3 on Windows 98 or NT, you receive the error "this filename is invalid".
Steps to reproduce:
1. Launch QuarkXPress and create a new document
2. Draw a picture box and assign it a color
3. Select File>Save Page As EPS and type in a name that is more than 8 characters long. When you click save, you will get the error message, "This filename is invalid".
4. This does not happen in Windows 95 or Windows 2000 RC2.
Note:
This problem occurs only when running QuarkXPress 3.32 under Windows NT 4.0. Windows 98 does not appear to be affected.
<b>Question :</b>
This is wierd. I am running Photoshop 5.5 on Windows2000. If I drag a .jpg file with a long filename,
9 plus characters, onto Photoshop, the file will open up into Photoshop with the correct name. If I
double click on a .jpg file with a long filename, it wil open with a shortend name.
Example: longfilename.jpg
Drag will open as "longfilename.jpg"
Double Click will open as "LONGFI~1.JPG"
This also happens with .eps files.
Any suggestions on how to make the file open correctly even when doubld clicked?
<b>Answer</b>
-Upgrade to Photoshop 6. I think whats happening is Photoshop 5.5 when checking back for the file soon
after it launches because of the program association & "see's" it as an 8.3 file...Why ? Because its
a little buggy on 2000. When you drag it into photoshop it does not do the same check name. A search
on adobe.com will show you that there are hundred's of 8.3 related bugs with jpg & eps files with 5.5
on 2000...The suggestion is always that its fixed when using version 6..
