See attached optimized version of your script (except MD5 code - it's original untouched, and also _SQLite_GetTable2d not used). use optimized MD5 hash calculation code -> search forum for examples use _SQLite_GetTable2d() instead of _SQlite_Query + _SQLite_FetchData -> I think it will be faster for big result sets - see next post from Kafu don't do DROP TABLE at end of script -> it's not needed in case of memory DB use _GUICtrlListView_BeginUpdate / _GUICtrlListView_EndUpdate -> smoother/quicker ListView display
don't assign $DataCol = GUICtrlCreateListViewItem() -> it's not used do INSERT INTO Duplicates in batch -> collect INSERTs into string variable and and call _SQLite_Exec() less times refresh progressbar and "Time Elapsed" only when it's neccessary -> avoid flicker/high CPU usage don't use Sleep (25) in main FOR NEXT loop don't calculate $sFileDate,$sDateStamp for small skipped files (skipped due to size filter) use BEGIN at start and COMMIT at end (without this each _SQLite_Exec will internally do commit transaction which slows down processing) use indexes for SQL tables (for columns used in WHERE)
