Yeah - but code outside of route handlers / hooks will run at initial
startup.  That can be useful though, to set stuff up.  In the example
you gave, the global var you set can then be used within routes etc.

A few comments on your code:

>          if ($fichier=~/\.xls$/i || $fichier=~/\.xlsx/i){
>                  my ($filename, $directory ) = fileparse($fichier);

>          }

You can match .xls/.xlsx in one regex with e.g.:

if ($fichier =~ /\.xlsx?$/i) {
    ...
}

You also missed anchoring to end of string in the second regex, so a
filename like fooxlsxfoo.jpg would match your check.

Also, you're going to look at every file you found and set $fichierXls
each time you find a spreadsheet file, so you'll end up with just the
filename of the last one found in $fichierXls.  It's not clear if
that's the desired behaviour or not.

Cheers
