Question on best practices for language pack handling: I use a process for Moodle updates where I download the latest en and en_us packs, and when I deploy Moodle updates I keep en.zip and en_us.zip in moodle/lang and also extract their contents to moodle/lang/en and moodle/lang/en_us. I then copy the entire moodle/lang folder to MoodleData/lang. Is any of this redundant or unnecessary?
What brought this to my attention was I just did a compare from our files to a new download of Moodle itself and all relevant extra plugins, and we keep many more files in moodle/lang/en. But does Moodle do any of the extraction? Our files are from a running system and I did not actually deploy and run the new file set.
