Please explain what you want in more detail. Is this a web application? Do you want to use FTP? or what?

Greetings.

If this is a web application:

i) for downloading, you need nothing more than a link to the appropriate file.

ii) For uploading, you can use CGI.pm, taking advantage of its multipart form support- it will do exactly what you want, from within a browser. CGI.pm's documentation is bundled with perl.

Cheers,

To upload the file you need something like:

<form enctype="multipart/form-data" action="http://server/accept.pl" method="post">
<input name="my_file" type="file">
</form>

Most browsers implement the the input type="file" tag with a button the brings up a file selector window.

In accept.pl have something like:

use CGI;
$query= new CGI;
$fileup = $query->param('my_file');

# extract its name
$strFilename = $fileup;
$strFilename =~ s/.*\\([^\s\\]+)$/$1/;

# build a name for the file on the server
$localFile =~ s/\\[^\s\\]+$//;
$localFile .= "\path\" . $strFilename;
 
# save the file
open (OUTFILE,">$localFile");
binmode($fileup);
binmode(OUTFILE);
while ($bytesread=read($fileup,$buffer,1024)) {
      print OUTFILE $buffer;
}

You will only need the binmode statements if the OS you are using diferentiates between text and binary files (eg windows, or at least the version that I'm using)
