Your current directory is "/" in the cRIO file system so your filename is relative to the root directory for relative paths. I have only successfully written to the root directory. Not all write operations generate files. Some generate errors that are visible on the Diagnostic screen of the the Driver Station. I am not certain that the first images retrieved from the camera are usable, but then I am still fumbling around.

I open a DOS window and use FTP to retrieve files from the cRIO. I just FTP to the ip address of the robot. "ls" returns a list of files. "get [filename]" retrieves a file to you current home directory. "delete [filename]" removes files. It appears to be a standard FTP implementation so you find documentation on the web.

I put a ".jpg" extension on the file when I write it out ("snapshot.jpg"). I can specify explicitly how to format the file using a specific imaqWrite*File method, so it may not matter except to indicate to Windows the format of the file. I do not know what format file the ImageBase::Write method generates (extension may be significant here).
