- The wxHTML library uses a @b virtual file systems mechanism
- similar to the one used in Midnight Commander, Dos Navigator,
- FAR or almost any modern file manager. It allows the user to access
- data stored in archives as if they were ordinary files. On-the-fly
- generated files that exist only in memory are also supported.

+Three classes are used in order to provide virtual file systems mechanism:

 
 

- @li The wxFSFile class provides information
-     about opened file (name, input stream, mime type and anchor).
- @li The wxFileSystem class is the interface.
-     Its main methods are ChangePathTo() and OpenFile(). This class
-     is most often used by the end user.
- @li The wxFileSystemHandler is the core
-     of virtual file systems mechanism. You can derive your own handler and pass
-     it to the VFS mechanism. You can derive your own handler and pass it to
-     wxFileSystem's AddHandler() method. In the new handler you only need to
-     override the OpenFile() and CanOpen() methods.

+Locations (aka filenames aka addresses) are constructed from four parts:

 
 

- @li @b protocol - handler can recognize if it is able to open a
-     file by checking its protocol. Examples are "http", "file" or "ftp".
- @li <b>right location</b> - is the name of file within the protocol.
-     In "http://www.wxwidgets.org/index.html" the right location is "//www.wxwidgets.org/index.html".
- @li @b anchor - an anchor is optional and is usually not present.
-     In "index.htm#chapter2" the anchor is "chapter2".
- @li <b>left location</b> - this is usually an empty string.
-     It is used by 'local' protocols such as ZIP.

- It is not used by global protocols like HTTP but it becomes handy when nesting

- file:archives/cpp_doc.zip#zip:reference/fopen.htm#syntax
- In this example, the protocol is "zip", right location is
- "reference/fopen.htm", anchor is "syntax" and left location
- is "file:archives/cpp_doc.zip".

- @li @b wxArchiveFSHandler:
-     A handler for archives such as zip
-     and tar. Include file is wx/fs_arc.h. URLs examples:
-     "archive.zip#zip:filename", "archive.tar.gz#gzip:#tar:filename".
- @li @b wxFilterFSHandler:
-     A handler for compression schemes such
-     as gzip. Header is wx/fs_filter.h. URLs are in the form, e.g.:
-     "document.ps.gz#gzip:".
- @li @b wxInternetFSHandler:
-     A handler for accessing documents
-     via HTTP or FTP protocols. Include file is wx/fs_inet.h.
- @li @b wxMemoryFSHandler:
-     This handler allows you to access
-     data stored in memory (such as bitmaps) as if they were regular files.
-     See wxMemoryFSHandler for details.
-     Include file is wx/fs_mem.h. URL is prefixed with memory:, e.g.
-     "memory:myfile.htm"
