The FileSystem manages files and archives and provides access to them.
It manages where files are, so that modules which use the the IO do not need to know where every file is located. A file could be in a .zip-Archive or as file on disk, using the IFileSystem makes no difference to this.

virtual void irr::io::IFileSystem::addArchiveLoader | ( | IArchiveLoader * | loader | ) | [pure virtual] |
Adds an external archive loader to the engine.
Use this function to add support for new archive types to the engine, for example proprietary or encrypted file storage.
virtual bool irr::io::IFileSystem::addFileArchive | ( | const path & | filename, | |
bool | ignoreCase = true , |
|||
bool | ignorePaths = true , |
|||
E_FILE_ARCHIVE_TYPE | archiveType = EFAT_UNKNOWN , |
|||
const core::stringc & | password = "" | |||
) | [pure virtual] |
Adds an archive to the file system.
After calling this, the Irrlicht Engine will also search and open files directly from this archive. This is useful for hiding data from the end user, speeding up file access and making it possible to access for example Quake3 .pk3 files, which are just renamed .zip files. By default Irrlicht supports ZIP, PAK, TAR, PNK, and directories as archives. You can provide your own archive types by implementing IArchiveLoader and passing an instance to addArchiveLoader. Irrlicht supports AES-encrypted zip files, and the advanced compression techniques lzma and bzip2.
filename,: | Filename of the archive to add to the file system. | |
ignoreCase,: | If set to true, files in the archive can be accessed without writing all letters in the right case. | |
ignorePaths,: | If set to true, files in the added archive can be accessed without its complete path. | |
archiveType,: | If no specific E_FILE_ARCHIVE_TYPE is selected then the type of archive will depend on the extension of the file name. If you use a different extension then you can use this parameter to force a specific type of archive. | |
password | An optional password, which is used in case of encrypted archives. |
