Problems Using the XCOPY Command and Long Filenames (134768)


The information in this article applies to:

  • Microsoft Windows 95
This article was previously published under Q134768

SYMPTOMS

When you use the XCOPY command, files with long filenames may not be copied.

CAUSE

If the "Prevent MS-DOS-based programs from detecting Windows" option is enabled for the MS-DOS prompt, the XCOPY command does not copy files with long filenames.

Also, long filename support is not enabled in MS-DOS mode, Safe mode, or Command Prompt Only mode. Note that no MS-DOS command will move a file with a long filename in MS-DOS mode.

RESOLUTION

If the "Prevent MS-DOS-based programs from detecting Windows" option is enabled for the MS-DOS prompt, follow these steps to disable it:
  1. Use the right mouse button to click the MS-DOS Prompt icon, and then click Properties on the menu that appears.
  2. On the Program tab, click the Advanced button.
  3. Click the "Prevent MS-DOS-based programs from detecting Windows" check box to clear it.
  4. Click OK.

MORE INFORMATION

Do not manipulate long filenames outside of Windows 95. When you boot to a command prompt, support for long filenames is not enabled.
