This way, you do not have to deal with files at all. Regards, Karsten -----Ursprüngliche Nachricht----- Von: Nicolas Maisonneuve [mailto:[EMAIL PROTECTED] Gesendet: Donnerstag, 15. Januar 2004 13:28 An: [EMAIL PROTECTED] Betreff: Copy Directory to Directory function ( backup) hy , i would like backup a index. 1) my first idea is to make a system copy of all the files but in the FSDirectory class, there is no public method to know where is located the directory. A simple methode like public File getDirectoryFile() { return directory; would be great; } 2) so i decide to create a copy(Directory source, Directory target) method i seen the openFile() and createFile method but after i but i don't know how use it (see my function , this function make a Exception ) private void copy (Directory source, Directory target) throws IOException { String[] files=source.list(); for(int i=0; i<files.length; i++) { InputStream in=source.openFile(files[i]); OutputStream out=target.createFile(files[i]); byte c; while((c=in.readByte())!=-1) { out.writeByte(c); } in.close(); out.close(); } someone could help me please nico --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
