File names for locker texts in the Rockett games always include a letter or group of letters that determine which "book" (i.e. background, hence the thread title) they appear in. This is always the second group of characters in the file name. In Tricky, there's a handful of these, but by Dance, most of them were dropped in favor of the Whistling Pines journals. (Whether this was because development was rushed or to make things more streamlined, I can't say.)
Not all locker items with text in them are included as text files. Some non-journal/diary items (the Camp Pine-Away brochures, Viva's astrology book, etc.) appear to just be stored as graphic files.
Also of note: There is one locker text file in Tricky that doesn't follow the normal naming format: a journal entry from Nicole vowing revenge against Rockett and everyone who humiliated her in the gym scene; labeled "~1.txt".
Here are the ones I've encountered, for easy reference.
AB - "Address book", used by multiple students.
BB - Nicole's "boy book".
CJ - "CSG Journal". Miko's customized journal with the CSG logo on it (not to be confused with the private report book).
D - Nicole's "diary" in Tricky; Mavis' secret notebook in Invitation and Dance.
FJ - Nakili's private journal in Tricky. "Family journal"?
J - "Journal". Specifically, the green Whistling Pines planner found in almost everyone's lockers. Most text written by characters are labeled with this.
LB - "Log book". Used exclusively by teachers. The teacher version of "J" texts.
MJ - "Main journal", entries for Rockett's personal journal (in her backpack) in Invitation and Dance.
N - "Note", anything written to a character (students and teachers), not by them. Can be anything from notes sent by other people to official school correspondence. The background used for any given note seems to be determined elsewhere in the game's coding.
NB - Mr. Pill's personal "notebook".
PJ - Sharla's "private journal".
PRB - The CSGs' "Private Report Book".
RB - Ruben's (blue spiral) notebook.
SB - Mavis' "Secret [Note]Book" in Tricky.
T - To-do lists written by Max and Whitney. Presumably uses one of the notepad backgrounds.
TD - Nicole's to-do lists.
TG - Hints for the "truth glasses" scavenger hunt segment.
The text for Rockett's backpack journal are kept in a separate folder (RESOURCE/shared2 in Tricky, RESOURCE/idbackpk in Invitation and Dance) and use a different file name format in Tricky. ("bpjournal[scene#][emotion abbreviation]" or "pbjournal[scene#[emotionabbrev.]"). In Invitation and Dance, they follow the same naming scheme as other locker texts.
Presumably, New School uses a similar scheme to Tricky for its graphic files, but I haven't been able to dig into those yet.
