For example because there are too many files under a directory.
In this situation we can use SSH to delete a directory and all files and subdirectories under that directory.

We can use the command below.
But be careful, do not enter wrong path.
You may delete the wrong directory. 🙂

How to Install PECL Memcache in WHM / CentOS
You can run these commands to install PECL memcache (not memcached).
However, this memcache will work with memcached.
```
wget http://pecl.php.net/get/memcache-3.0.8.tgz
tar xvfz memcache-3.0.8.tgz
cd memcache-3.0.8
phpize
./configure
make
make install
```
Take note of the php extensions directory that memcache is installed in.
Mine is: /usr/local/lib/php/extensions/no-debug-non-zts-20020429/

Then add this line to your php.ini
```
extension="/usr/local/lib/php/extensions/no-debug-non-zts-20020429/memcache.so"
```
