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:
- Use the right mouse button to click the MS-DOS Prompt icon, and then
click Properties on the menu that appears.
- On the Program tab, click the Advanced button.
- Click the "Prevent MS-DOS-based programs from detecting Windows" check
box to clear it.
- 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.
