It is from the DOS version of FoxPro 2.6.

The command I am trying to run is:

datadest = destination drive
m.path= path of source files
m.splfiles = source file range

comand_line = "COPY "+m.splfiles+" "+datadest


!/0 &command_line

Once the program executes the copy statement gets so far the error "Cannot create Directory Entry" appears.
