If you receive an error relate to unknown getAccounts.

Then try change the aura attribute in componment as follow and try again. 
<aura:component controller="AccountsController">
  <aura:attribute name="accounts" type="List" />
to 
<aura:component controller="AccountsController">
  <aura:attribute name="accounts" type="Account[]" />

 

Hi,

There is an standard object called File. If i want to import and export files in the file object using data loader i cannot do it because File object is not there in the list in Data Loader. Please tell me how to export and import files.
