Cannot uploade windows image backup (VHDX image)


I created a Azure storage, installed Azure Storage Explore. Account is set up with an blob container. I can upload files. But I can not get it to upload a VHDX image about 15GB.

Should I set up further to transfer a VHDX image located in a folder on the C: Image is a restored backup from an external drive with Azure backup from server 2012.

Receiving error message:
Error uploading the file: The process can not acces the file!

I can upload any other files in windows backup folder Which is recreated with Azure backup to a folder on the C: drive. just not VHDX image
