Last change on this file since 1481 was 1480, checked in by Gregg Young, 16 years ago

Fix failure to correctly check for large file support in FindSwapperDat fall back code minor streamling. Add LVM.EXE to partition submenu. Stop using xDosQueryAppType where the file name it is passed is already a local stack variable. Correct a typo in several file header comments.
