Minecraft LCE Save Format
NOTE
Data in this format is endian-dependant and also commonly has compression applied to it.
Check out Basic Info.md for more info.
For the pre-release (Xbox 360 Edition versions 0033 and 0035) save file, check out Pre-Release Save Format.md.
The Save File is a container of subfiles that make up the entire save... One can think of it as a Java world folder but as a single file.
Save file structure
| Name | Size (in bytes) | Description |
|---|---|---|
| Offset | 0x04 (uint) | Offset of File information |
| File count | 0x04 (uint) | Number of Files in list of File Info |
| Minimum version | 0x02 (ushort) | Minimum file version (assumed) |
| File version | 0x02 (ushort) | Version of the save file |
| File data | Variable | bytes of each file contained inside the save |
| File info | Variable (144 * File count) | File names, file offsets, file sizes, and modified timestamps. |
The File Information is stored in a table at the bottom of the file, with 1 entry for each file. (who could've guessed)
File Information
| Name | Size (in bytes) | Description |
|---|---|---|
| File Name | 0x80 | UTF16 UNIX-style path string to dictate the path of the file |
| File Size | 0x04 (uint) | Size of the file in bytes |
| Offset | 0x04 (uint) | Offset of the file (inside the container) in bytes |
| Timestamp | 0x08 (ulong) | Last modified timestamp of file, although unusable due to arbitrary values being used for the generation of the timestamp. |
