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.

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.
|
pure virtual |
Adds an archive to the file system.
After calling this, the Jimcpp 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 Jimcpp 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. Jimcpp 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. |
retArchive | A pointer that will be set to the archive that is added. |

Jimcpp supports AES-encrypted zip files, and the advanced compression techniques lzma and bzip2. If you want to add a directory as an archive, prefix its name with a slash in order to let Jimcpp recognize it as a folder mount (mypath/). Using this technique one can build up a search order, because archives are read first, and can be used more easily with relative filenames.

len | The length of the memory in bytes |
fileName | The name given to this file |
deleteMemoryWhenDropped | True if the memory should be deleted along with the IWriteFile when it is dropped. |

pure virtual |
Creates a XML Reader from a file which returns all parsed strings as wide characters (wchar_t*).
Use createXMLReaderUTF8() if you prefer char* instead of wchar_t*. See IIrrXMLReader for more information on how to use the parser.

archive | The archive to remove. |
|
pure virtual |
Removes an archive from the file system.
This will close the archive and free any file handles, but will not close resources which have already been loaded and are now cached, for example textures and meshes. Note that a relative filename might be interpreted differently on each call, depending on the current working directory. In case you want to remove an archive that was added using a relative path name, you have to change to the same working directory again. This means, that the filename given on creation is not an identifier for the archive, but just a usual filename that is used for locating the archive to work with.
filename | The archive pointed to by the name will be removed |
