Microsoft Azure Storage Explorer recently updated to version 1.13.0 and updated AzCopy to 10.4.2. With this update, a bug was introduced inadvertently with a change within the client SDK for Azure. Essentially, when copying a file, instead of:
1 https://(storage account).blob.core.windows.net/(container)/folder/file.doc
You’ll now see and
/ after the container decoded as
1 https://(storage account).blob.core.windows.net/(container)/folder%2Ffile.doc
Navigating that URL will not resolve properly. Microsoft is aware of this issue and is working on a resolution. In the meantime, replace the
%2F values with
/ so the file will load properly.
