Cached files in typo3temp/

TYPO3 caches files (merged configuration data, scripts, ...) in typo3conf/. This directory looks like this:

-rw-r--r--    1 httpd    httpd       27501 Jan 29 18:35 temp_CACHED_ps2d95_ext_localconf.php
-rw-r--r--    1 httpd    httpd       83513 Jan 29 18:35 temp_CACHED_ps2d95_ext_tables.php

There can be more than just these files, because of multiple paths, symlinks or just old files.

You can at any time remove these files and on the next website request they will be regenerated. These files simply contain all ext_tables.php and ext_localconf.php files from the installed extensions concatenated in the order they are loaded. Therefore, including one of these files would be the same as including potentially hundreds of PHP-files; and concatenating them saves a few on each request.

But that also means that changes to these files don't persist and, when you make changes to the original ext_tables.php/ext_localconf.php files, you will have to delete these files.
