+I typed the following to copy ka1.mp3 to my home directory...
+cp /var/public/unix/ka/ka1.mp3 ~/Documents
+To discover what type of file ka1.mp3 is, I typed...
+file ka1.mp3
+Which told me...
+ka1.mp3: POSIX tar archive (GNU)
+So, using tar, I extracted the file within by typing...
+tar -xf ka1.mp3
+And got the file lvl300.mudkip.gen3.dat.gz which I used gzip to extract...
+gzip -d lvl300.mudkip.gen3.dat.gz
+Which gave me the file lvl300.mudkip.gen3.dat which I wasn't sure what to do with. Running the "file" command told me this was a ZIP archive. Since the file ends with the suffix ".dat" gzip won't let me extract the files from within. This is where "unzip" must be utilized as below...
+unzip lvl300.mudkip.gen3.dat
+And now I have a folder called "unix-ka1" which contains 5 files; brute, genhash.c, hashfile, match, and process.

+Some of this was slightly answered above but I can answer again! The files are listed below along with their "type" based on what the file command tells me.
+        brute: Bourne-Again shell script text executable
+        genhash.c: ASCII C program text
+        hashfile: ASCII text
+        match: Bourne-Again shell script text executable
+        process: Bourne-Again shell script text executable
+I can cat all of these files, don't-cha-know.
+x4:
+To compile the .c file, type the following:
+gcc genhash.c -o genhash
+To run it:
+./genhash
+This program generates encrypted text from the user input.
