Bloom.WebLibraryIntegration.BookTransfer.S3BookId C# (CSharp) Method

            // But this complicates things because that character is taken as a path separator (even in Windows),
            // which gives us an extra level of folder in our temp folder...too much trouble for now, anyway.
            // So use a different separator.
