DOS directory jumping tools = find it, go to it, use it.

PP.COM Push/Pop jumps2 a dir from a choose menu.
STR.COM finds strings in a dir /s /b c:\*.* > menu.txt for PP.com
STRNOT.COM removes lines with string, from INfile & writes2 OUTfile.
MGOTO.COM creates a.bat file that returns to the dir it was made in.

FREEware FASM source code included.

README.TXT = a bit more help,
for those that know, DOS is a stable programming environment where you can write for any OS,
and then test your executable on another machine running any OS off a CD.
