File upload path in Alfresco share content

[success]

Hi,guys!
     I'm an newcomer in Alfresco study.And I'm always have a doubt in my mind: The content I uploaded from Alfresco share store where? the database? or Is there  exists a file server to support the file upload and download? but I found that in the database alfresco ,there is a table called
alf_content_url,and there is  a  field called content_url ,but the format is '.bin',and i can't find any direct ,apparent file path stored in alfresco,when I want download a file ,I can't get the file url ,the problem puzzled me fairly a long time.
    you quickly reply will be looking forward.and i'll show greatly appreciate to your help.the answer i want to get  is that you can offer me a method to get  the path or an explaination to the path that i uploaded in the Alfresco share  Document Library. I'm eager for get a detailed ,apparent , direct file directory ,thank you very much .

Files are uploaded in contentStore (alf_data folder) in your fileSystem.

Metadata (name of your file for example) are stored in your database.

At first ,thank you  very much for you quick reply.
       if thing are like you says,there is another obstacles in front of me.if I want download a file ,How can I get the the Alfresco install  directory ? Before we access the ContentStore(alf_data fileSystem) ,we should get the Alfresco install directory. and How can I get the install directory ?
By window regedit ?but there is some permissions to operate the regedit. or we can obtain it by the other ways ?I'll always waiting for your answers online!
      through the answer you replied me ,I find the suffix of fileNames that stored in the contentStore are end with 'bin' ,and the FileName are different from the origin name of the file ,I doubt that after I upload a file ,whether there is necessary or not to  transfer the filename format?
by what means? only i get the content url can i download the file ,thks.

In summary , the core ideas in my problem is that how can I assign a content url when I download a file through a hyper?  the UI present a hyper when i click it then down load the file that located in the content url that i had distributed. thks.
