If File Exists

If File Exists makes available to developers the c2c_if_file_exists() WordPress-specific PHP function that can be used to check the presence of a file in the upload directories.

Variants of the function are also available to check for files in the themes and plugins directory as well:
c2c_if_theme_file_exists()
c2c_if_plugin_file_exists()

If the file the developer was searching for is not found, the function returns "0".

If the file is found, the function returns "1", along with information about file name, file disk path and file URL.

The plugin does not have a visual interface and is basically a programming tool for WP developers.

Installation:

Unpack and upload it to the /wp-content/plugins/ directory.
Activate the plugin through the 'Plugins' menu in WordPress.
