This would be the decimal value of the file status code being returned.

You can translate this by opening up the Windows Calculator in Programmer mode and then entering the decimal value and converting it to hex to get the two status code byte values.

In this case, 2361 decimal = 09 39 hex and since this is little endian system you would reverse the bytes so the status is 39 09 hex.

A 39 hex translates to a "9" ASCII character which means the second byte is a RTS error which would be 9.

If you look up RTS error 9 in the docs it says:

COBRT009 Directory not found (Recoverable)

The system cannot write to the specified directory for one of the following reasons:

The directory does not exist

The directory is full

Your program cannot find the directory

This error usually occurs when the specified directory contains a space. If that is the case, then you need to enclose the directory with double quotations, e.g. "C:\\My Directory\\Subdir\\aFile.ext"
