Using the files' URL starting with "http://" or "https://", you can make files in a shared folder accessible from kintone.
To do this, place files in a location that can be accessed with an "http://" or "https://" URL (e.g., internal server), and then specify the URL on kintone.

The following example explains how to place a file in a location that can be accessed with an "http://" URL and make the file accessible from kintone.

• Server machine name
  cybozu
  
  

• Home directory of the Web server
  c:\Inetpub\wwwroot
  
  

• File location
  c:\Inetpub\wwwroot\share\test.png
  
  

• URL of the file
  http://cybozu/share/test.png
  Specify this URL in the Announcement section, threads, "Link" fields, or anywhere you want. Clicking the URL allows you to access the file.
