Problem with the browser in a CGI written in Perl

Are you using a webserver here?  Is the USB device on the server, or the client?  If, in HTML, you have a file input type, it will be displayed with a browse button in the web browser.

The Wx is a module to give you a graphical interface - it does not work within CGI.

The <input type = "file" .../> element does not work for me because you can not select a directory (only files) and also you can not set up the initial directory /media/usbdisk. So I think it is not enough solution.

The  Wx::Perl::BrowseButton control seems to be enough, but the installation of the Wx module failed.

Are there any other posibility, perhaps a custom popup that shows the directories under /media/usbdisk/?

What are you trying to do?  It isn't clear what should happen on the client, and what on the server.

Well, I have a touch screen PC that runs in exhibition centers. I need that when a user insert a pen drive or a SDCard the application shows a new screen that show a checkbox list with the files to download to the USB, also I need to give the user the option to choose the destiny directory in the USB disk to download.

I implemented a CGI with Perl that is shown only when the pen drive is inserted. Now I need to show the directory tree because the user needs to say where to copy the selected files.

Anyone can assist me with the directory browser control, now I am thinking in display a new CGI page that acts as a browser.

Thanks in advance
