5 Simple Steps to Delete Salesforce files Owned by Other Users

In Lightning Experience, we have limitation who can Delete Files - 
Only a File Owner and Users with the “Modify All Data” permission can delete all Files !!!
This is working as designed for Lightning version.

 We recently moved from Salesforce Classic to Lightning Experience .

 While transition to Lightning Experience, we have enabled "Save Email-to-Case attachments as Salesforce Files" Email-to-Case Settings and also enabled "Files uploaded to the Attachments related list on records are uploaded as Salesforce Files, not as attachments" from Salesforce Files Settings.

 So whenever we receive attachments in Email-to-Case or Upload any attachment into Salesforce, it automatically convert into files by Salesforce.

 We have business process setup where we have to delete some confidential files received via Email-to-Case. In this blog I am going to explain how I achieve this.

 To meet requirement, we have only one option available which is Customization.

 I have used one idea, "Whenever Case Owner changes then Set that Owner as an Owner for Files of that Case".

 If you similar business process then Follow below 5 Simple Steps :

 1. Create Apex class namely "ContentDocumentController" with Without Sharing and add below code:

public without sharing class ContentDocumentController {
// Call below method from Case process builder
@InvocableMethod
public static void changeFileOwners (List<ID> caseIds){
callFutureMethod(caseIds);
}
@future
public static void callFutureMethod(List<ID> caseIds) {
Id caseOwnerId;
List<Case> lstCase = new List<Case>();
try{
// Fetch all Cases with EmailMessages (Incoming and Outgoing)
lstCase = [SELECT OwnerId,(SELECT id FROM EmailMessages) FROM Case WHERE Id IN :caseIds];
Set<Id> sharedId = new Set<Id>();
sharedId.addAll(caseIds);
for(Case objcase:lstCase){
caseOwnerId = objcase.OwnerId;
for(EmailMessage em: objcase.EmailMessages)
sharedId.add(em.id);
}
List<ContentDocumentLink> lstContentDocumentLink = new List<ContentDocumentLink>();
// Fetch ContentDocumentLink for Case and EmailMessages
lstContentDocumentLink = [SELECT ContentDocumentId FROM ContentDocumentLink WHERE LinkedEntityId =:sharedId];
// Check if Case and EmailMessage have files as an Attachment
if(!lstContentDocumentLink.isEmpty()){
Set<Id> setContentDocument = new Set<Id>();
List<ContentDocument> lstContentDocument = new List<ContentDocument>();
for(ContentDocumentLink objCDL: lstContentDocumentLink)
setContentDocument.add(objCDL.ContentDocumentId);
lstContentDocument = [SELECT ID, OwnerId FROM ContentDocument WHERE ID IN :setContentDocument];
// Sync Case Owner with File Owner
if(!lstContentDocument.isEmpty()){
for(ContentDocument objCD: lstContentDocument)
objCD.OwnerId = caseOwnerId ;
UPDATE lstContentDocument;
}
}
}
catch(Exception ex){
// If any exception occures send exception email to Administrator.
sendErrorEmail(caseIds,lstCase[0].OwnerId,ex.getMessage());
}
}
public static void sendErrorEmail(List<Id> caseId, Id caseOwnerId, String errMsg){
Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();
String subject = 'Error while changing File Owner, Case Id- '+caseId+', New Owner- '+caseOwnerId;
email.setSubject( subject );
email.setToAddresses( new String[] {'nitish.talekar@testabc.com'} );
email.setPlainTextBody( errMsg );
// Sending email
if(!Test.isRunningTest())
Messaging.SendEmailResult [] r = Messaging.sendEmail(new Messaging.SingleEmailMessage[] {email});
}
}

2. Create Process builder on Case object for INSERT / UPDATE event.
3. Define Criteria for this Action Group : 
 AND(
  NOT(ISNEW() ),
  ISCHANGED([Case].OwnerId ),
  BEGINS([Case].OwnerId, "005") 
 )
4. Set below things as Immediate action:


5. Activate Process Builder.

<aura:component>
    <!--use boolean attribute for Store true/false value,make default to "false" so modal box are not display on the load of component. --> 
    <aura:attribute name="isModelBoxOpen" type="boolean" default="false"/>
    
    <!--Use "slds-m-around_xx-large" class to add standard X-Large padding to the component--> 
    <div class="slds-m-around_xx-large">        
        <lightning:button variant="brand" 
           label="What is Lightning Modal/PopUp Box?" 
           title="What is Lightning Modal/PopUp Box?" 
           onclick="{! c.openModel }" />
        <!--Use aura:if tag to display Model Box, on the bese of conditions. [isModelBoxOpenboolean attribute] -->   
        <aura:if isTrue="{!v.isModelBoxOpen}">            
            <!--###### MODAL BOX Start######--> 
            <section role="dialog" tabindex="-1" aria-labelledby="modal-heading-01" aria-modal="true" aria-describedby="modal-content-id-1" class="slds-modal slds-fade-in-open">
                <div class="slds-modal__container">
                    <!-- ###### MODAL BOX HEADER Start ######-->
                    <header class="slds-modal__header">
                        <lightning:buttonIcon iconName="utility:close"
                           onclick="{! c.closeModel }"
                           alternativeText="close"
                           variant="bare-inverse"
                           class="slds-modal__close"/>
                        <h2 id="modal-heading-01" class="slds-text-heading_medium slds-hyphenate">Lightning Modal/PopUp Box</h2>

                    </div>
                    <!--###### MODAL BOX FOOTER Part Start ######-->
                    <footer class="slds-modal__footer">
                        <lightning:button variant="neutral" 
                           label="Cancel"
                           title="Cancel"
                           onclick="{! c.closeModel }"/>
                        <lightning:button variant="brand" 
                           label="Ok"
                           title="Ok"

            <!--###### MODAL BOX Part END Here ######-->            
        </aura:if>
    </div>
</aura:component>

ModelDemo.js => Lightning Js Controller Code

({
   openModel: function(component, event, helper) {
      // for Display Model,set the "isModelBoxOpen" attribute to "true"
      component.set("v.isModelBoxOpen", true);
   },
   closeModel: function(component, event, helper) {
      // for Hide/Close Model,set the "isModelBoxOpen" attribute to "False"  
      component.set("v.isModelBoxOpen", false);
   },
   submitBox: function(component, event, helper) {
      // set the "isModelBoxOpen" attribute to "False for close the model Box.
      component.set("v.isModelBoxOpen", false);
   },
})
ModelDemo.App => Lightning component App

 
<aura:application extends="force:slds">
    <c:ModelDemo/> <!-- here c: is org. namespace prefix-->
