16-Bit Applications May Not be Able to Use Long Filenames

• Microsoft Windows NT operating system version 3.1
• Microsoft Windows NT Advanced Server version 3.1

SUMMARY

When you are running 16-bit Windows or MS-DOS applications under Windows NT, you may receive various error messages when trying to save a file to an NTFS partition using a long filename. 16-bit applications are not designed to use filenames greater than the 8.3 characters that MS-DOS allows. Some 16-bit applications may allow you to save long filenames, some may give incorrect or misleading error messages and still save the file as an 8.3-character filename.

It may be possible to use a long filename with a 16-bit application if you save the file as an 8.3-character MS-DOS filename and then rename it with File Manager. However, some applications, such as Write, will rename the file back to 8.3 characters when it is saved.

MORE INFORMATION

For example, if you try to save a long filename in Word for Windows, you will receive the following error message:

   This is Not a Valid Filename.

In Write, if you try to save a file as THISFILEHASALONGFILENAME.WRI to an NTFS partition, you will receive the following error message:

   x:\THISFILEHASALONGFILENAME.WRI
   Cannot Find This File.

   Either Something Has Happened to the Network or Possibly the File
   Has Been Renamed or Moved. Do You Want to Try Again?

With the MS-DOS editor (EDIT.COM), if you save a file with a filename greater than 8.3 characters, Edit will take the first 11 characters of the supplied name and use it for the 8.3 filename.
