copy uploaded file and some data to a text file using jquery

Dear Friends,   I want to upload a file and along with that i want to save some information i.e. document name and document type and comments. but i want

to do all these with jquery. i don't want to use any server side coding , by using jquery or any other client side scripting i want to save the uploaded file to a folder in local system and save some information into a text file.

and then i want to read the same and will show in the html  page.  

All these i want to do for a mockup..

could you please tell me the way to read and write the data to a text file and to copy and read the file from a folder (in local system only)

Thanking you..
