| − | == General Information ==
| |
| − |
| |
| − | The old engine cache is made up two types of files.
| |
| − |
| |
| − | === Data file ===
| |
| − |
| |
| − | The data file holds all of the files in the cache and is named '''main_file_cache.dat'''. It is therefore very big, typically ~10-20 megabytes.
| |
| − |
| |
| − | === Index file ===
| |
| − |
| |
| − | There are several index files, named '''main_file_cache.idx''' and then postfixed with a number. Each index file holds 'pointers' to where a file is located in the main cache. Each index file represents a type of file.

| |
| − | === Index file format ===
| |
| − |
| |
| − | The index file is made up of 6 byte blocks which hold information about where a file can be located in the data file. The format of a single block is as follows:
| |
| − |
| |
| − | tribyte fileSize
| |
| − | tribyte initialDataBlockId
| |
| − |
| |
| − | === Data file format ===
| |
| − |
| |
| − | The data file is made up of 520 byte blocks. The format of each of these blocks is as follows:
| |
| − |
| |
| − | short nextFileId
| |
| − | short currentFilePartId
| |
| − | tribyte nextDataBlockId
| |
| − | byte nextFileTypeId
| |
| − | byte[512] blockData
