* The library file for the file cache store.
* This file is part of the file cache store, it contains the API for interacting with an instance of the store.
* This is used as a default cache store within the Cache API. It should never be deleted.

$string['singledirectory_help'] = 'If enabled files (cached items) will be stored in a single directory rather than being broken up into multiple directories.<br />
Enabling this will speed up file interactions but comes at the cost of increased risk of hitting file system limitations.<br />
It is advisable to only turn this on if the following is true:<br />
- If you know the number of items in the cache is going to be small enough that it won\'t cause issues on the file system you are running with.<br />
- The data being cached is not expensive to generate. If it is then sticking with the default may still be the better option as it reduces the chance of issues.';
* This is is like the file store, but designed for siutations where:
* - many more things are likely to be stored in the cache, so CRC hashing is
* too likely to give collisions, and storing everything in a completely flat
* directory structure is inadvisable.
* - the things we are caching are more expensive to calculate, so the extra
* time to computer a better hash is a worthwhile trade-off.
