Hi Jose, 
  
Greetings from Syncfusion support. 
                                                                        
We have validated your reported problem, but unfortunately we were unable to reproduce it at our end as the download operation of File Manager component is working fine in the v19.0.1.66.  
  
We have attached our validated demo sample for your reference below. 
  

If your reported problem still persists, then please share us the following information. 
  
  • Let us know which file provider service that you are using with FileManager component in your application.

  • If possible, replicate your reported problem above provided sample or provide us a simple sample to replicate the issue.
  
  • Share your issue reproducing browser with version.
  • Which .Net(.net 3.1/ .net 5.0) version you have used in your application
