'\' marks special meaning for some following characters. For example '\n'
means a linebreak. But if there's no special meaning for a character (for
example '\g') the '\' is taken as a 'normal \'. Where do your ps_file or
pdf_file come from ? Is it possible that they contain special escape
sequences like '\n' or '\t' like 'myFolder\test.txt' ? To check this simply
write a 'print cmd' befor you call 'os.system(cmd)'. Does the string looks
like you expected it ?
