Skyrim Mod:Mod File Format/TES4
The UESPWiki – Your source for The Elder Scrolls since 1995
TES4 is the header record for the mod file. It contains info like author, description, file type, and masters list. Record flags indicate the following:
- 0x1: if set, the file is treated as a master, regardless of what the file extension says.
- 0x80: whether the file has localized string tables. If this flag is not set, lstrings are treated as zstrings.
- 0x200: if set, the file is treated as a light master.
|+||INTV||uint32||Number of strings that can be tagified (used only for TagifyMasterfile command-line option of the CK).|
|-||INCC||uint32||Some kind of counter. Appears to be related to masters.
