An incomplete filename was entered. If either a drive or folder is specified, then both must be specified. For example, the following two filenames are incomplete:
C:LHA.EXE
\UTILITY\LHA.EXE
In the first example, a drive is specified but no folder is specified. This can cause unexpected errors if you change the current folder on the C: drive.
In the second example, a folder is specified but no drive is specified. This can cause unexpected errors if you change the current drive.
Specify a filename like C:\UTILITY\LHA.EXE instead. Note that if the file is in a folder specified by your PATH= environment variable you do NOT need to enter a drive and folder.
