Ненамного сложнее, но возможностей поболе будет.

procedure ScanDir (Path:string;SearchMask:TStrings;ScanSub:boolean);
var
SearchRec:TSearchrec;
a,i:integer;
begin
if ScanSub then
begin
FindFirst(path+'\*.*',faDirectory,SearchRec);{. found}
FindNext(SearchRec); {.. found}
a:=FindNext(SearchRec);
while a=0 do
begin
if (SearchRec.Attr and faDirectory)>0 then 
 
ScanDir(Path+'\'+SearchRec.Name,SearchMask,ScanSub);
a:=FindNext(SearchRec);
end;{while}
FindClose(SearchRec);
end;{if}
 
for i:=0 to SearchMask.Count-1 do
begin
a:=FindFirst(Path+'\'+SearchMask[i],faAnyFile,SearchRec);
while a=0 do
begin
{operation on file}
a:=FindNext(SearchRec);
end;{while}
FindClose(SearchRec);
end;{for}
 
end; {ScanDir}
