You need to prepend the directory name to your file name, just like the documentation for readdir advises. Change: 
    open (FIC, $fichier) or die "Impossible d'ouvrir le fichier ", "$f
+ichier : ", "$!";

to: 
    open (FIC, "$dossier/$fichier") or die "Impossible d'ouvrir le fic
+hier ", "$fichier : ", "$!";

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
