Can I download a file stored in storage bucket from UiPath App interface?

Can I download a file stored in storage bucket from UiPath App interface using Get File From Storage Activity?

Maybe this will help:

Sorry, I missed the premise of your question.

When the file is downloaded with the Rule you have used above, the file must be assigned to an AppVariable

Once the file is downloaded the AppVariable will be populated with a lengthy URL, that is a direct link to the file in the Storage bucket that I have simulated here:

https://…blob.core.windows.net/orchestrator-GUID/BlobFilePersistence/GUILD/FILENAME?sv=2020-04-08&st=2021-11-23T19%3A41%3A18Z&se=2021-11-23T20%3A41%3A48Z&sr=b&sp=r&sig=U9lJdclASfDpyBXq8J2lOYsazwpIn4Pu37NoyV5qvbc%3D&fileName=FILENAME

You can then use that URL as shown in the screen grab below to open the file in the Browser (or assign it to a Filepicker with Download Only enabled)

Here below, I either use the file picker , or I have an alternate link to open the file in a Browser. For debugging purposes I have put the downloaded file URL in a textarea box.
