# Archive/Help/Version compatibility

From XOWA: the free, open-source, offline wiki application

| Note: This page is obsolete. It is preserved for historical reference only.

XOWA tries to maintain version compatibility across releases -- both forward compatibility and backward compatibility.

As a result of this strategy, certain files/directories may be created that are no longer used anymore. If you have questions about these files, or just want to delete them, you should consult the sections below.

## as of v0.2.2

- /bin/any/javascript/math is no longer used. It may be deleted. The new location is /bin/any/javascript/xowa/math
- /xowa/user/anonymous/app/data/*.csv is no longer used. Any files here may be deleted. The new location is /xowa/user/anonymous/app/data/history/*.csv.

## as of v0.2.1

- siteInfo.xml and wiki.gfs are no longer used. They may be deleted. The new replacements are wiki_core.gfs and wiki_stats.gfs. For an example, see /xowa/wiki/simple.wikipedia.org/cfg.
