>On my XP for years I have been using a little DOS program TS.EXE (which I believe was part of Norton Utilities) that allows to quickly search any file for a string of text. This program (TS.EXE) does not work on Windows 7 64-bit (I just got this message when trying to run this program for the first time; it said, "not compatible with 64-bit"). Do you know if Windows 7 has this type of utility or tool built in? TIA.
