Title: Files/Directories
Question: How can delete a directory with its files and subdirectories?
Answer:
In Delphi there is a function called RemoveDir that delete empty directories. But what about directories that has files and sub-sub... directories?
For this reason I implemented my own function to act like the normal RemoveDir function but with extra functionality to delete any files or subdirectories in side that directory.
Function MyRemoveDir(sDir : String) : Boolean;
var
iIndex : Integer;
SearchRec : TSearchRec;
sFileName : String;
begin
Result := False;
sDir := sDir + '\*.*';
iIndex := FindFirst(sDir, faAnyFile, SearchRec);
while iIndex = 0 do begin
sFileName := ExtractFileDir(sDir)+'\'+SearchRec.Name;
if SearchRec.Attr = faDirectory then begin
if (SearchRec.Name '' ) and
(SearchRec.Name '.') and
(SearchRec.Name '..') then
MyRemoveDir(sFileName);
end else begin
if SearchRec.Attr faArchive then
FileSetAttr(sFileName, faArchive);
if NOT DeleteFile(sFileName) then
ShowMessage('Could NOT delete ' + sFileName);
end;
iIndex := FindNext(SearchRec);
end;
FindClose(SearchRec);
RemoveDir(ExtractFileDir(sDir));
Result := True;
end;
Example:
if NOT MyRemoveDir('D:\myDir') then
ShowMessage('Can NOT delete dir');
Note:
(1) Any system/hidden/read-only files will be deleted.
