Hi, The other day I was creating a few large zip files on my 20g D: drive. The files were 3 and 4 GB respectively. When I tried to copy the files to my 40g E: drive I get an error message stating something like 'unable to copy - invalid parameter' Apparently Fat32 supports the file size as I can read it, extract and compare it ... I just cannot copy. Is this a artificial restriction in file copy? An artifact of earlier windows routines? Any ideas how to move these files? I want to move the 20g to another computer. thanx in advance for any insights
