Die Funktion ermittelt unter Windows und Linux (Ubuntu) ob das Verzeichnis leer ist:
uses
SysUtils;
...
function funIstVerzeichnisLeer(strVerzeichnis: string): boolean;
var
srDatensatz: TSearchRec;
intI: integer;
begin
Result := False;
FindFirst(IncludeTrailingPathDelimiter(strVerzeichnis) + '*', faAnyFile, srDatensatz);
for intI := 1 to 2 do
if (srDatensatz.Name = '.') or (srDatensatz.Name = '..') then
Result := FindNext(srDatensatz) <> 0;
FindClose(srDatensatz);
end;Aufruf unter Windows:
function funTest: string;
begin
if funIstVerzeichnisLeer('D:\Test') = True then
Result := 'Leer'
else
Result := 'nicht Leer';
end;Aufruf unter Linux (Ubuntu):
function funTest: string;
begin
if funIstVerzeichnisLeer('/home/user/Test') = True then
Result := 'Leer'

Result := 'nicht Leer';
