[urgent] Why upload "ALL" files?
 

I just downloaded 3.8.2 version of vBulletin and to upgrade is says I have to upload "ALL" files in folder upload . I have a few questions, cuz this makes me REALLY REALLY confused.

- what if the customer already edited some default files inside the upload since previous version?
- is it really necessary to upload and replace all my old files with these new files?
- can I just run the upgrade.php without upload the new files?
- didn't vB developers think about people with edited files? because I don't see any notes about that. :confused:

I forgot how many files I have edited.
