Hi Alain, you string pattern is nuts. ""~~ ..... A string expression that starts with the empty string is superfluous. ToString[NAME2]*".jpg" * is the multiplication operator, hardly what you want. What you want is e.g.: ToString[NAME2]~~__~~".jpg" This means: the string in NAME2, followed by any sequence of one or more characters, followed by ".jpg" Daniel Alain Mazure wrote: > Hi again > > I have several files with extension .jpg of the type > > "C1822_8_025_1.jpg", "C1822_8_025_2.jpg" > "C1943_11_025_1.jpg", "C1943_11_025_2.jpg" ..... > > I know the first part of the name which was given by : "" ~~ > ToString[NAME2] with NAME2: C1822, C1943 ... > > How to use FileNames in order to have, for a given NAME2 all the *.jpg > files in order to import them ? > > The command: FileNames["" ~~ ToString[NAME2]*".jpg"] does not work > > Thanks !!! > > > > > > > > > > Alain Mazure > > Laboratoire d'Astrophysique de Marseille > P=F4le de l'=C9toile Site de Ch=E2teau-Gombert > 38, rue Fr=E9d=E9ric Joliot-Curie > 13388 Marseille cedex 13, France > > http://alain.mazure.free.fr/ > > Mails: > alain.mazure at oamp.fr > alain.mazure at free.fr > > Phones: > Lab: 33(0)491055902 > Mobile: 33(0)603556287 > Fax: 33(0)491661855 > SKYPE: MAZURE-ALAIN >
