I have an exe which convert postscript file to text now the problem is when input file name contain spaces it says "GPL Ghostscript 9.00: Unrecoverable error, exit code 1" but no problem when output file contains no spaces. I am running the following command in a bat file
pstotxt3.exe -bboxes -output "2dh 21za1.1jp.ps.pstotext.txt" "2dh 21za1.1jp.ps"
where 2dh 21za1.1jp.ps.pstotext.txt is the output file name and 2dh 21za1.1jp.ps is the input file name
Try double quoting the input filename. I'm not familiar with pstotxt3, but it looks like it is running GS as a separate process, and passing the input filename as a command line parameter. The " marks on the command line to pstotxt3 get stripped by the command processor, so when GS see the filename it thinks they are multiple switches.
So I'd suggest: pstotxt3.exe -bboxes -output "2dh 21za1.1jp.ps.pstotext.txt" ""2dh 21za1.1jp.ps""
But that's merely a guess. Can you post the complete error please ?
