Hi Jose,
Greetings from Syncfusion support.
We have validated your requirement with FileManager component. But, we were unable to replicate your reported problem as download functionality in FileManager working properly without any issues. When selecting more than one folder in FileManager and click on download button in the toolbar, it will download all the folder in zip format.
For your reference, we have prepared a Hosted Web Assembly application of FileManager component using latest version of Syncfusion.Blazor (19.1.0.69).
Please, refer the below sample link.
If your reported problem still persists, then please share us more details regarding your reported problem.
· Share us the video footage of your reported problem.
Please, let us know, if you need any further assistance.
Regards,
Sowmiya.P
