First of all, I am not familiar with webserver.... What I did was:

1) Run QuickPHP Webserver (I choose it for now because it is lightweight and no installation needed... If it is not good enough, please recommend something better but...please easy...)

2) Extract and copy COPS folder to the root folder of QuickPHP
3) Copy everything in the "example" file to the config file, and edit the path to Calibre database ($config['calibre_directory'] = 'F:\PortableApp\Calibre Portable\NQK Bookshelf\/'

4) try: http://localhost:5723/
it returns as follows

Warning: Cannot modify header information - headers already sent by (output started at F:\Data\Clouds\Dropboxs\checkconfig.php:3) in F:\Data\Clouds\Dropboxs\checkconfig.php on line 15

Check if Calibre database file can be opened with PHP

If the file is readable, check your php configuration. Exception detail : exception 'PDOException' with message 'could not find driver' in F:\Data\Clouds\Dropboxs\checkconfig.php:205 Stack trace: #0 F:\Data\Clouds\Dropboxs\checkconfig.php(205): PDO->__construct('sqlite:F:\Porta...') #1 {main}

Check if Calibre database file contains at least some of the needed tables

If the file is readable, check your php configuration. Exception detail : exception 'PDOException' with message 'could not find driver' in F:\Data\Clouds\Dropboxs\checkconfig.php:218 Stack trace: #0 F:\Data\Clouds\Dropboxs\checkconfig.php(218): PDO->__construct('sqlite:F:\Porta...') #1 {main}

And I would like to ask if I need to sync all files in COPS folder to dropbox? php server to dropbox? together with Calibre library.... I can't get it to work yet so I'm still a little bit confused
