Gostaria de saber se existe , ou algum modo de fazer, uma procedure no delphi que busque um determinado arquivol qualquer no HD !
Por exemplo: Gostaria de procurar o arquivo casa.bmp , então a função me retornaria o caminho onde está o arquivo : C:\Arquivos\Imagens\casa.bmp
Agradeceria muito a ajuda !!! Valews !!!

Tente assim:

var
  Form2: TForm2;

type
   PRecInfo=^TRecInfo;
   Trecinfo=record
   prev:PRecInfo;
   fpathname:string;
   srchrec:Tsearchrec;
end;

implementation


procedure TForm2.Button1Click(Sender: TObject);
var 
l1:Tstringlist; 
begin
   l1:=tstringlist.create;
   listbox1.items.clear;
   listbox1.Items.BeginUpdate;
   l1:=recursedirectory(´D:\*.gif´);
   listbox1.items.assign(l1);
   freeandnil(l1);
   listbox1.Items.endUpdate;
end;

function TForm2.RecurseDirectory(fname: string): tstringlist;
var 
   f1,f2:Tsearchrec;
   p1,tmp:PRecInfo;
   fwc:string;
   fpath:string;
   fbroke1,fbroke2:boolean;
begin
   result:=tstringlist.create;
   fpath:=extractfilepath(fname);
   fwc:=extractfilename(fname);
   new(p1);
   p1.fpathname:=fpath;
   p1.prev:=nil;
   fbroke1:=false;
   fbroke2:=false;
   while(p1<>nil) do
      begin
      if (fbroke1=false) then
         if (fbroke2=false) then
            begin
            if (findfirst(fpath+´*´,faAnyfile,f1)<>0) then
