A general thing to note is that packing files this way overwrites the WHOLE file, whereas modding the standard way will only overwrite specific entries. For example, a packed mod may have a Data.txt file that only has the 4-5 parameters it modfiies, but the loose version needs the whole Data.txt file with the modified parameters integrated in it.
Right! That's why you need to be very careful about what you overwrite, since you can inadvertently mess up the base game and create bugs or crashes.
Before I renamed my localization files, when I would get to the character creation screen, the first character it generated was invisible. This was from my localization files overwriting something. Weird bug.
