I need to be able to save a list of about 300 - 600 filenames(names will get added and removed). I'll need to be able to search this list for matching files. What would be the best method to get this done? Save the filenames to a text file and then load them into an array, use a database, ini file, or what. I'm not sure which is best.

Thanks

Hi,
Use a TStringList, it's easiest.

var
  MyList: TStringList;
  iIndex: iIndex;
.
  MyList := TStringList.Create;
  MyList.Sorted := True; // optional
  MyList.Add( Filename1 );
  MyList.Add( Filename2 );
  MyList.Add( Filename3 );
  for iIndex := 1 to MyList.Count-1 do begin // only on sorted list!!!
    if CompareText( MyList[ iIndex ], MyList[ iIndex - 1 ] ) = 0
    then ... // found duplicate!
  end;
  MyList.SaveToFile( 'MyFiles.txt' ); // save list to file
  MyList.LoadFromFile( 'MyFiles.txt' ); // load list from file
  MyList.Free; // destroy list

That's it!
