Detailed Description

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.

Member Function Documentation

◆ addArchiveLoader()

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.

◆ addFileArchive() [1/3]

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 = `""`,
		IFileArchive **	retArchive = `0`
	)

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.

Parameters

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.

Returns: True if the archive was added successfully, false if not.

◆ addFileArchive() [2/3]

virtual bool irr::io::IFileSystem::addFileArchive	(	IReadFile *	file,
		bool	ignoreCase = `true`,
		bool	ignorePaths = `true`,
		E_FILE_ARCHIVE_TYPE	archiveType = `EFAT_UNKNOWN`,
		const core::stringc &	password = `""`,
		IFileArchive **	retArchive = `0`
	)

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. If you want to add a directory as an archive, prefix its name with a slash in order to let Irrlicht 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.

Parameters

file	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.

Returns: True if the archive was added successfully, false if not.

◆ addFileArchive() [3/3]

virtual bool irr::io::IFileSystem::addFileArchive ( IFileArchive * archive )

pure virtual

Adds an archive to the file system.

Parameters

archive The archive to add to the file system.

◆ addFolderFileArchive()

virtual _IRR_DEPRECATED_ bool irr::io::IFileSystem::addFolderFileArchive	(	const c8 *	filename,
		bool	ignoreCase = `true`,

	)

inlinevirtual

Adds an unzipped archive (or basedirectory with subdirectories..) to the file system.

Deprecated:: This function is provided for compatibility with older versions of Irrlicht and may be removed in Irrlicht 1.9, you should use addFileArchive instead. Useful for handling data which will be in a zip file

Parameters

filename	Filename of the unzipped zip archive base directory 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.

Deprecated:: This function is provided for compatibility with older versions of Irrlicht and may be removed in Irrlicht 1.9, you should use addFileArchive instead. After calling this, the Irrlicht Engine will search and open files directly from this archive too.

◆ removeFileArchive() [1/3]

virtual bool irr::io::IFileSystem::removeFileArchive ( u32 index )

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.

Parameters

index The index of the archive to remove

Returns: True on success, false on failure

◆ removeFileArchive() [2/3]

virtual bool irr::io::IFileSystem::removeFileArchive ( const path & filename )

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.

Parameters

filename The archive pointed to by the name will be removed

Returns: True on success, false on failure

◆ removeFileArchive() [3/3]

virtual bool irr::io::IFileSystem::removeFileArchive ( const IFileArchive * archive )

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.

Parameters

archive The archive to remove.

Returns: True on success, false on failure

◆ setFileListSystem()

virtual EFileSystemType irr::io::IFileSystem::setFileListSystem ( EFileSystemType listType )

pure virtual

Set the active type of file system.
