Find out total size of directory
You should specify a directory. After that, you should find all files in this directory by recursion. You should add to the total size the size of each found file.
procedure TForm1.Find(Str: string);
var
MySearch: TSearchRec;
FindResult: Integer;
begin
FindResult:=FindFirst(Str+'\*.*',
faArchive+faHidden+
faAnyFile+faVolumeID+
faSysFile+faReadOnly+faDirectory,
MySearch);
while FindResult=0 do
begin
if (MySearch.Attr=faDirectory) and
(MySearch.Name<>'.') and
(MySearch.Name<>'..') then
Find(Str+'\'+MySearch.Name)
else
TotalSize:=TotalSize+MySearch.Size;
FindResult:=FindNext(MySearch);
end;
FindClose(MySearch);
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
TotalSize:=0;
if Length(Edit1.Text)>0 then
begin
Find(Edit1.Text);
Label2.Caption:='Total size = '+IntToStr(TotalSize);
end;
end;
procedure TForm1.Button2Click(Sender: TObject);
var
St: string;
begin
St:='c:\';
if SelectDirectory(St, [], 0) then
Edit1.Text:=St;
end;
