Put that filename in quotes. Most folks just specify files without the drive letter.

Boyer Sent: Tuesday, August 30, 2011 9:56 PM To: brailleblaster@xxxxxxxxxxxxx Subject: [brailleblaster] Problem with BrailleBlaster on Windows I have set up BrailleBlaster so that if a file name is given on the comand line right after the jar file it will open that file. This was done so that files with the extension .utd (UTDML file) could be associated with BrailleBlaster and would open automatically. However, when I tried this on Windows with the file name c:\brl-books\emphasis.xml the file would not open because the backslashes had been removed. Doubling them resulted in single backslashes in the file name, but this defeats file association. What is the workaround for this? Thanks, John -- John J.
