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

hi, i checked on the file, it's not read only.  but the pst file has a password before it can be opened to outlook.  does it have an effect?  i'm trying to remove the password via outlook but an error msg appears that password could not be changed. pls advise.  thx

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.

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.
