What is the purpose of the %%xx folders under files/civicrm/templates_c/en_US?  They cause a major headache any time I try to move data from a local machine to the server.  Even if I get the database imported successfully, when I go to a screen, I get errors like this:
    * user error: Smarty error: unable to write to $compile_dir '/home/campfire/public_html/files/civicrm/templates_c/en_US'. Be sure $compile_dir is writable by the web server user. in /home/campfire/public_html/sites/all/modules/civicrm/packages/Smarty/Smarty.class.php on line 1095.
    * warning: Smarty::include(/home/campfire/public_html/files/civicrm/templates_c/en_US//%%DB/DB1/DB10BE01%%Group.tpl.php) [function.Smarty-include]: failed to open stream: No such file or directory in /home/campfire/public_html/sites/all/modules/civicrm/packages/Smarty/Smarty.class.php on line 1871.
    * warning: Smarty::include() [function.include]: Failed opening '/home/campfire/public_html/files/civicrm/templates_c/en_US//%%DB/DB1/DB10BE01%%Group.tpl.php' for inclusion (include_path='.:/home/campfire/public_html/sites/all/modules/civicrm:/home/campfire/public_html/sites/all/modules/civicrm/packages:.:/usr/lib/php:/usr/local/lib/php') in /home/campfire/public_html/sites/all/modules/civicrm/packages/Smarty/Smarty.class.php on line 1871.
In this case, somebody screwed up my web server, and the entire server had to be rebuilt.  The en_US/%%DB directory isn't even there now, so I get the error message above.  By chance is there a simple way to get around these errors when moving between servers?  They're a real headache.

Thanks.
