bonjour

Je developpe une petite application qui doit trouver un fichier sur n'importe quel partition.

Hors je ne sais pas sur quel partition se trouve le fichier.

Comment puis-je récupérer la liste des noms des partitions

la liste serait par exe^mple c: d: f: ....


merci d'avance

la methode listRoots de la classe File pourrait t'interresser :

listRoots

public static File[] listRoots()

List the available filesystem roots.

A particular Java platform may support zero or more hierarchically-organized file systems. Each file system has a root directory from which all other files in that file system can be reached. Windows platforms, for example, have a root directory for each active drive; UNIX platforms have a single root directory, namely "/". The set of available filesystem roots is affected by various system-level operations such as the insertion or ejection of removable media and the disconnecting or unmounting of physical or virtual disk drives.

This method returns an array of File objects that denote the root directories of the available filesystem roots. It is guaranteed that the canonical pathname of any file physically present on the local machine will begin with one of the roots returned by this method.

The canonical pathname of a file that resides on some other machine and is accessed via a remote-filesystem protocol such as SMB or NFS may or may not begin with one of the roots returned by this method. If the pathname of a remote file is syntactically indistinguishable from the pathname of a local file then it will begin with one of the roots returned by this method. Thus, for example, File objects denoting the root directories of the mapped network drives of a Windows platform will be returned by this method, while File objects containing UNC pathnames will not be returned by this method.

Unlike most methods in this class, this method does not throw security exceptions. If a security manager exists and its SecurityManager.checkRead(java.lang.String) method denies read access to a particular root directory, then that directory will not appear in the result.

Returns:
An array of File objects denoting the available filesystem roots, or null if the set of roots could not be determined. The array will be empty if there are no filesystem roots.

Salut,


Tu peux utiliser la méthode getRoots() de FileSystemView...

Elle te renvoit l'élément de base de l'architecture de la machine ('/' sous Unix/Linux, le 'Bureau' sous Windows, les différents disques sous DOS pur).

merci a vous


je n'ai eu le temps que de tester le listRoots ca marche très bien


encore merci
