How to? Use SYNC with a network drive

I am using;
TCC  20.00.17   Windows Vista [Version 6.0.6002]
TCC Build 17   Windows Vista Build 6002  Service Pack 2

I have a network drive, drive O:
TCC:6532: 25 > net use
New connections will be remembered.

Status       Local     Remote                    Network

OK           O:        \\\dosbox    Microsoft Windows Network
The command completed successfully.

I have full access to this drive, and the drive does exist;
TCC:6532: 27 > if exist o:\nul echo Yes

When I use the sync command,
which sync
sync is an internal command

as follows, it returns the following;
TCC:6532: 20 > sync /H /C /W /Z /S /G /V C:\Users\jlc\Documents\DOSBox O:\users\jlc\Documents\DOSBox
Usage : SYNC [/A:[[-][+]rhsdaecjot] /CDEGH /I"text" /JKLM /N[dejnst] /O:[-]adegnrstu /OPQR /Sn /TVWX] dir1 di

When I use the sync command on a local drive (F:), the sync completes correctly;
TCC:6532: 26 > sync /H /C /W /Z /S /G /V C:\Users\jlc\Documents\DOSBox F:\users\jlc\Documents\DOSBox
SYNC: C:\Users\jlc\Documents\DOSBox => F:\users\jlc\Documents\DOSBox

     0 files copied
SYNC: F:\users\jlc\Documents\DOSBox => C:\Users\jlc\Documents\DOSBox

     0 files copied

I have been using the Microsoft Sync Toy and drive O: with no problems;


Why can I not sync to my O: drive using the SYNC command?

I can't reproduce that here, unless either the source directory or the target directory doesn't exist. (SYNC will not try to create the target directory.)

If the directories exist, SYNC will display its "SYNC:..." message and begin copying files. Since you're not getting that, I suspect that your target doesn't exist or you don't have access privileges.
Well, Microsoft SyncToy works, so I will continue to use it.

I could not reproduce an error.

SYNC: V:\empty => O:\

:facepalm: Well, fudge muffins...

Instead of using;
sync /H /C /W /Z /S /G /V C:\Users\jlc\Documents\DOSBox O:\users\jlc\Documents\DOSBox

I should have been using;
sync /H /C /W /Z /S /G /V C:\Users\jlc\Documents\DOSBox O:\

Works as documented now.
