Offline (HTML+CSS+PHP) File/Documents Database for local

I created a HTML+CSS+PHP web template. I'm planning to create a offline file/documents database. I'm thinking of a web based or access the files through html.

Functions : Upload file to html and store it to directory/folders.

View Files with different category (for example : ".docs" only) Delete files Add comments/reminders to files Date uploaded Number of days file stored

Is it possible? Or any other way to do it? Adding/ Viewing/Deleting file in a local folder through html/ offline web?
