DOS Power Tools: Techniques, Tricks and Utilities is a book by Paul Somerson, first published in 1988 by Bantam Books and sponsored by PC Magazine. The book offers a guide to approaching MS-DOS (and its cousin PC DOS) as well as various tricks and utility programs—the latter provided as x86 assembly source code listings and as compiled .COM and .EXE executables on an accompanying floppy disk (later expanded to three disks). The book was a best-seller and received positive critical reception.
