How to increase attachment file size in Qlik Sense

[Sonja_Bauernfeind]

According to the Qlik Sense online help, the total available space for file attachments maximizes at 200 MB: Attaching data files and adding the data to the app.

However, it is possible to increase this size with QRS API.

! Warning: Please note that increasing this size to a high number might impact performance and must be used carefully.

There are some concerns about attaching data file. Please refer to online help for your respective version. 

Environment:

1. Install Postman. Please note that you have to install the Chrome version, not the Windows(Desktop) version.
2. Open the hub or the QMC in Chrome and authenticate to Qlik Sense.
3. Run Postman from Chrome.
4. In case Windows authentication is used, log in to the hub or QMC in Chrome first and turn on Interceptor in Postman. You may need to install the add-on for this.
    
5. Add parameters. You need to have Xrfkey and X-Qlik-Xrfkey. In this case, Xrfkey/X-Qlik-Xrfkey is 12345678qwertyui. This can be any 16 digit character string.
   
6. Run GET command to get element. Type URL as follows: 
   
   https://serverName/qrs/appcontentquota/full?Xrfkey=12345678qwertyui
   
   * Xrfkey must be the same than X-Qlik-Xrfkey for each request.
   
   
   
   
7. You will get a response as below. Copy it.
   

   {"id":"1001a995-e85d-4ecd-aa17-b66f3ac20c43","createdDate":"2017-03-14T05:13:33.287Z","modifiedDate":"2017-03-22T07:44:43.716Z","modifiedByUserName":"DOMAIN\\administrator","customProperties":[],"maxFileSize":52428800,"maxLibrarySize":209715200,"privileges":null,"impactSecurityAccess":false,"schemaPath":"AppContentQuota"}​

8. Change the method from GET to PUT and add id to URL.
   
   i.e. https://serverName/qrs/appcontentquota/1001a995-e85d-4ecd-aa17-b66f3ac20c43?Xrfkey=12345678qwertyui
   
   * id is in GET response. Copy the "id" value.
   
   
9. Paste above response in Body. Select json(application/json). You can modify maxFileSize and maxLibrarySize.
   
   maxFileSize is the max file size for each file.
   maxLibrarySize is total space.
   
   
10. Run PUT request. Check status. It should be "200 OK".
    
    
    
    
11. Run step 6 GET command again for confirmation.
12. Go to hub and open any application. Check available space.
    
    
    
    * This change applies to all apps. However this file space is for each app.
