+## tar.bz2
+
+Let’s say you have an extra-large directory that you want to compress as much as possible.
+If tar.gz results in an over-sized file, try using tar.bz2 instead. Note that this option does take a little
+longer.
+
+This archive method adds only one new option: -j, as shown in the following example:
+
+`tar -jcvf <archive name>.tar.bz2 /directory/to/compress`
+OR
+`tar -jcvf <archive name>.tar.bz2 ‘*.jpg’`
+
+Again, to extract a .tar.bz2 file, switch the -c for -x, as shown in the following examples:
+
+`tar -jxvf <archive name>.tar.bz2`
+OR
+`tar -jxvf <archive name>.tar.bz2 -C /directory/to/extract/to/`
