File List

There are many different blocks that are aimed at loading files. Their data do not save in items_list. There is a separated array for that called file_list. In this chapter we will see what data about files is used in the application.

For each loaded file will be saved all needed data about it.

Name	Type	Description
app_id	`number`	due to this property, file is saved in the application folder
extention	`string`	saves file extension; used in generating a new name
file_id	`number`	saves generated by the server identification number for file
file_name	`string`	initial file name saves in this property; in the future, it is not used since a new name is generated
item_id	`number`	shows which item this file belongs to
last_update	`number`	shows last time of file update in milliseconds
url	`string`	shows path to the file on the server

Name Generation

At first, server generates an identification number for file. Then server merges it with the extension and saves as a new file name.

Saving Files On The Server

Let’s look at url. It consists of three parts:

https://gudhub.com/userdata/26503/872421.jpg

Base URL: https://gudhub.com/userdata/

Application ID: 26503

File name created by the server: 872421.jpg
