The specified blob does not exist - Shows in azure browser - but when I click download does not exist

Question

I've uploaded some blobs to azure. They show in the browser when I log in, but when I attempt to download them I get following message:

This XML file does not appear to have any style information associated with it. The document tree is shown below.

I think I know why you're running into this issue. I believe its an issue with the portal. If you notice, the name of your blob is: Tommy French Toals.North Street.1250251 and it contains spaces. However if you look at the URL the name is coming as: Tommy%2520French%2520Toals.North%2520Street.1250251. Notice the presence of %2520. What portal software is doing is that it is performing URL encoding twice - first, it URL encodes space in the blob name to %20 and then again URL encodes the % sign to %25 and this is messing things up for you.

Just to be double sure, I uploaded a file which contains spaces in its name in my storage account and when I try to download the blob through the portal, it failed with the same error as yours. Then I created a SAS URI for the same blob using storage client library, and it worked perfectly fine. Here's the code I used for creating SAS URI:

        CloudStorageAccount storageAccount = new CloudStorageAccount(new StorageCredentials("myaccount", "myaccountkey"), true);
        var blobContainer = storageAccount.CreateCloudBlobClient().GetContainerReference("mycontainer");
        var blob = blobContainer.GetBlockBlobReference("this file has spaces in its name.txt");
        var sas = blob.GetSharedAccessSignature(new SharedAccessBlobPolicy()
        {
            SharedAccessExpiryTime = DateTime.UtcNow.AddHours(1),
            Permissions = SharedAccessBlobPermissions.Read,
        });
        var sasUrl = blob.Uri.AbsoluteUri + sas;

Try downloading a file which does not contain spaces or any special characters in its name and it should work just fine.
