I am the author of BugHunter. I'd like to clear up a couple of misunderstandings...
BugHunter doesn't require you to copy it to drive C:, I use that as an example in the FAQ file. You can carry it around on a USB stick, or copy it to a ram disk of sufficient size to hold it's temporary data files, and run it from there.
I have pasted a copy of the default configuration file BUGHUNT.INI which comes with the program.
I hope this clears up the misunderstanding.
; BugHunter v2.x configuration file sample.
; The commands, APPEND, CREATE, NOLOG, and FULL can be placed
; anywhere inside this file you like. The command YES can also be
; placed anywhere inside the file you like, but the following two
; lines must be present below it: locate.com and parameters,
; and the name of the temporary file BugHunter should use.
; Default settings are full recursive scan, a logfile will
; be created in the current directory if possible.
; the default temporary file is BUGHUNT.DAT and will be created
; in the current directory. Logging options are as follows
; APPEND = Append to the already existing BUGHUNT.LOG (if present)
; otherwise one will be created.
; CREATE = Create a new logfile each time an option is performed.
; NOLOG = Exactly what it says.
No logfile is created. No logging
; to file takes place if one already exists.
; FULL = Log extra details. How many files in each folder, location
; and name of any files that couldn't be opened for scanning. Some files
; that are in use will cause this error.
; is turned off by default. Log files can grow to large sizes if this
; option is switched on. However, it does provide extra detail.
; YES controls recursion. If using YES, the following two lines MUST
; be the name location and parameters of locate.com (default is current
; directory bughunter is executing from) and the name of the temporary
; file for use.
locate.com /D+ /N /R
; As BugHunter is preset to do full recursion, this section of the
; configuration file is ignored. If you would like BugHunter to scan
; the folders listed below (you may customize them as you see fit; upto
; 32 folders) can be specified in the msdos 8.3 style naming convention.
; Comment yes and the two lines below it. To re-enable full recursion,
; simply uncomment yes and the two lines below it.
; These directories assume a default installation of C:\WINDOWS. If you
; are not using full recursion, please modify the directory paths to
; suit your system configuration. By Default, BugHunter will not just
; scan the directories listed below. Full recursion is turned on, and
; this section of the configuration file is ignored.
