Program to big to fit in memory

Jeg arbejder med VBA til Access, og når jeg kører:
Shell ("command.com /c c:\test.bat")
som er en batch fil som kopiere,sletter og omdøber nogen filer. Den kan slette og omdøbe filer men den vil ikke kopiere dem. Den melder istedet Program to big to fit in memory.
Nogen der kan give mig en løsning på problemet?

English translation:
Im working with VBA for Access, and when I run:
Shell ("command.com /c c:\test.bat")
which is a batch file who copies, deletes and renames files. It can delete and rename files, but it would not copy them. It says Program to big to fit in memory.
Is there somebody who can give me a solution to my problem?
