I would like to use the methode mentioned by Leledumbo with TFileSearcher, because this seems to be the easiest one
How do I have to define the OnFileFound-Event? This does not work:
Search.OnFileFound := ShowMessage('File found:' + sLineBreak + Search.FileName);
@Takeda:
Where can I download Trunk of Lazarus?
I could not find any download-page...
@Bart:
Your backup-tool is very complex, I am confused by the many functions and procedures :S
Thank you for the replies again and Greetings,
