As a Salesforce Marketing consultant, you have been mandated to implement Marketing Cloud and need to do a demo for a workshop. To prepare this demo, you need to add data to your already created data extension. Let’s look at the screenshot below: I am trying to add data to my data extension “DE TEST”.  When doing so, this error message appears, and the import fails: “Error : Upload Error uploading, decompressing, or decrypting the file” This error occurred because there was no FTP account created. You need to add a new FTP account and re-attempt the import. Follow these steps to add a new FTP account: Log into your account Hover over your name in the top right corner and select Administration Click on Accounts Click on FTP User Click on Create User Enter a password Save Hoping this article will help you, see you soon with a new post! Live with pleasure! Cornelia
