Cannot coy [filename] invalid MS-DOS function

Dear Experts,

I'm copying my 2.1GB pst file from my drive C to the folder of a shared computer.  However, when around 49% has already in progress, i get the error message, Cannot coy mails1.pst invalid MS-DOS function.  Copying therefore does not proceed.  Please advise how do I go about the copying.  Thanks

you could try using xcopy "source" "destination" /variables.

Or a nice free little utility is fsplit. Pick your file, designate how many chunks you want to divide it up into (or size) and it creates a batch file to put them back together. Copy all the files over then execute the batch file. Also a great way to break them down to cd size data chunks for burning onto disc.

Most of this case is related with bad cd's.

I think copy command may has some limitations. What's your computer and the shared computer's soft environment ? (including OS version, partiton format: NTFS ? FAT32 ? FAT?)

You can try to use a compress tool such as WinRAR to compress the pst file, and then move the compressed file to the new location.
