VIEW THE COMMUNITY FILENAME PREFIX RESERVATION LIST

Conditions:

• Please register only one prefix. If you want more than one, please give a reason.
• ONLY two-letter prefixes can be registered. (Note: prefixes that had been registered before this rule came into force were not deleted; they are still valid.)
• If you want to register a prefix, check if there isn't a 3-letter prefix already that starts with the same letters as yours (e.g. it's useless and may cause prefix conflict if you register 'XQ' if 'XQP' is already registered by someone else).
• Your prefix will be in the Personal prefixes section (even if you register it in the name of a whole mod project). The Projects section is legacy, no new prefixes are added there.
• Please write a few words about your upcoming mod(s) where you plan to use the prefix. There are a lot of prefixes registered, and the community often does not hear about new released mods where these prefixes are used. This is why we ask for a few thoughts about your modding plans with the prefix you request.

In the Status field of the prefix list table, you can meet four types of status:
'OK' - the prefix is unique, it has no conflict with any other prefixes
'Conflict' - the prefix or the significant part of it is registered by more than one people, and it may cause incompatibility. This type of prefix conflict is relatively common
'Global Conflict'- one-letter prefixes. These have been registered for a long time. Now, registering one-character prefixes is not possible.
'Protected' - These are usually filename prefixes used by modding communities (example: G3, BW).
