Hi,
I want to create a macro that writes files in a sub directory. If the directory is already created, things work fine. However, if the directory is not there, tex complains

Please type another output file name:
Is there a way I can ask tex to create a directory if one does not exist?
Not with TeX, but you can use \write18 or \installprogram to run a system command.
Can I ask TeX to check if a directory exists or is writable. I want it to give an informative message if the directory does not exist. Or is there a way to check if a file is writable, so that I can do \doiffilewritable{dir/tempfile}{\donothing}{\message{Warning}{Please create directory 'dir' \endinput} Aditya
