We have a NetApps 740 running 5.3.7R2.  We run NT on our workstations.  One of our people wrote a VB program that uses a filecopy command to take a file from an NT workstation and copy it multiple times, each copy with a different name, to a filer share.  According to him, if he copies a series of files and the first file is greater than 10K, it will successfully copy the remaining files with no error.  If the file is less than 10K, he gets a "file path error" copying the first file, but the file will have copied.  The error causes his VB program to halt.  Any thoughts out there?
