- TITLE :Cannot Access 8.3 Filename from MS-DOS-Based Application
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:buglist3.10
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1
- ----------------------------------------------------------------------
-
-
- SYMPTOMS
- ========
-
- From an MS-DOS or 16-bit Windows-based application, you are unable to
- access a filename on a FAT or NTFS (over the network) partition that
- has 8 characters before the period and 3 after (8.3 file format).
-
- CAUSE
- =====
-
- You created an illegal (under MS-DOS) filename using the Copy command
- from Command Prompt. On FAT partitions, you can use spaces and other
- illegal characters. On NTFS partitions, if you use the 8.3 filename
- format, no MS-DOS-compatible filename is created, even if you use
- illegal characters.
-
- All 32-bit Windows NT applications, such as Notepad and File Manager
- are able to access and manipulate these files because they have
- built-in long filename support. However, these files cannot be
- accessed by 16-bit MS-DOS or Windows-based applications either from
- Windows NT, MS-DOS, or Windows 3.1.
-
- Steps to Reproduce Problem
- --------------------------
-
- 1. Run Command Prompt from the Main group of Program Manager.
-
- 2. Type the following command:
-
- copy con "bad name.txt"
-
- 3. Type some text and press ENTER.
-
- 4. Press F6 or CTRL+Z.
-
- The resulting file will not be accessible from MS-DOS or 16-bit
- Windows-based applications.
-
- RESOLUTION
- ==========
-
- The only workaround is to rename the file using legal characters for
- MS-DOS from File Manager or Command Prompt.
-
- STATUS
- ======
-
- Microsoft has confirmed this to be a problem in Windows NT version 3.1
- and Windows NT Advanced Server version 3.1. We are researching this
- problem and will post new information here in the Microsoft Knowledge
- Base as it becomes available.
