Saving waveform on local USB stick- syntax error

I am using a set of DSOX3SGM, Segmented Memory Application for 3000 X - Series Oscilloscopes remotely operated by a LabWindows based DAQ system. Since transfer of data from all the oscilloscopes through TCP/IP connection takes long time, I want to save the waveforms to the respective USB drives I put on the scopes. I can do it manually. However, I want to do it through remote application in my program. I used following syntaxes:

:SAVE:WAVeform:FORMat ASCiixy
:SAVE:WAVeform:LENGth max
:SAVE:WAVeform:SEGMented ALL
:SAVE:WAVeform:STARt \\usb\test.csv

My first three commands executed successfully, but the fourth one never working.
It says INST Error -101, unrecognized character.

I am using C coding, I even printf the command which I sent, all different options, but no success.

Please help me, I know I am doing some silly mistake. Thank you very much for your help.

From the Programming Manual:

Command Syntax :SAVE:WAVeform[:STARt] []
::= quoted ASCII string

Try :SAVE:WAVeform:STARt "\\usb\test.csv"

Try a forward slash '/', instead of backslash '\'.

Use a :SAVE? Query to see what the current settings are, after resetting the scope. The result should have the forward slash in it.

Hello,

What is the correct answer? I have the same problem, it doesn't save the csv file. On the Scope it says
File name error

// Get CSV File
String csvPath1 = "\"MyData\"";
myScope.DoCommand(":SAVE:WAVeform:FORMat CSV");
myScope.DoCommand(":SAVE:FILename " + csvPath1);

ResultQuery = myScope.DoQueryString(":SAVE:Filename?");
richTextBox1.Text = Convert.ToString(ResultQuery); // it shows "MyData"

myScope.DoCommand(":SAVE:WAVeform:LENGth MAX ");

myScope.DoCommand(":SAVE:WAVeform:STARt "+csvPath1);

Best Regards,

Instead of:
:SAVE:WAVeform:STARt \\usb\test.csv

Try:
:SAVE:WAVeform:STARt "\\usb\\test.csv" (the editor is adding a CR. 2 backslashes after usb)

If the whole command is inside of a string try:

":SAVE:WAVeform:STARt \"\\usb\\test.csv\""

You have to set the drive first using the :SAVE:PWD command. For example:

:SAVE:PWD "\usb"

or

:SAVE:PWD "/usb"

Then do the save:

:SAVE:WAVeform:STARt "test.csv"

Note that both arguments are the SCPI data type quoted ASCII strings, so the quotes need to be sent to the scope to delimit the strings.
