2887.0. "Cannot copy large files from PC over Net" by TNPUBS::MARK () Wed Apr 02 1997 16:15

	We're having problems copying large .wav files from a PC to
a network drive on our cluster. These .wav files are quite large (60K blocks).

The user is trying to copy the files using copy/paste into a directory on
    the network drive and when it gets about half way thru the copy it bombs 
    out with th error message:
    
		"cannot create or replace filename.wav. The specified network
		resource or device no longer exists."

It is trying to copy to a network drive, but after I get this error message I 
do not lose my network connection to the drive, it is still there. I can copy
small files into this area, but it's these large files that will not copy. There
is plenty of space on the network disk, so this is not the problem.
The user states that this has worked in the past, but now it is not.

    My PC is running WIndows 95.
    
    
Any suggestions, ideas?

    	60K is a little bitty file ... 1M is a rather large file.
    
    	What sort of connection are you using to do the copy?

    Why not use drag and click as opposed to copy/paste?  60K may be too
    much for the clipboard.

    I interpreted the question as using ^C (copy) and ^V (paste) in
    Windows 95 Explorer, which is a lot more convenient than mousing it
    in that you don't have to arrange to have the source file and
    destination directory on the screen at the same time.
    
    This doesn't put the whole file in the clipboard; I've used ^C or ^X
    with ^V to copy or move multi-megabyte files within Explorer.
2887.4I may have seen this too?CHEFS::TREVENNOR_AA child of initWed Apr 02 1997 18:5512
    I've seen a similar problem in a different context. The drive sharing
    between Win95 systems gives exactly this problem if there are lots of
    files in a directory. For example if the Windows directory is well
    populated with files you can see the remote Windows directory, explore it's
    contents - but try dragging and dropping a file into it (even if it its
    fully non-password protected shared) and you get exactly this error.
    You could easily try to create a temporary empty top level directory
    and try dragging and dropping the file into it to see if that gives the
    same problem.

	What usually goes into the clipboard is not the file but
	a pointer to the file. I've copied 100s of MB at time and
	I doubt that all 100+ MB get copied to the clipboard. The
	pointers do tho.

    have you tried doing this using xcopy in a DOS window?? (If in doubt
    use DOS)

2887.8Use MS-DOS commands in Win95 for copying large filesTBB2::GRENFELLWed Apr 23 1997 00:2214
    I echo Leigh's comments about using the MS-DOS commands.
                                                   
    In our Windows 95 /  PATHWORKS for VMS V4.2 ECO08 environment we can
    never copy large files from the PC's hard disk or CD-ROM drive to a
     file-service inside the
    'Windows Explorer' by dragging files from one window to another. However
    the files can always be copied with the 'COPY' or 'XCOPY' command from an
    MS-DOS Prompt window.
    
    I have captured the traffic in IRIS and cannot see why the PC stops
    sending.
