<--This issue drove me nuts this week. Someone uploaded a bunch of ISO images with vCloud Director 5.5\. The ISO's images uploaded fine but some images appeared as normal and others appeared as icons with a question mark that are unmountable on VM's. WTF?

So I tried a couple things. I noticed that the ISO images were missing the .iso file extension. I tried renaming the ISO images through vCloud. No Love!

## How to fix Unknown ISO files in vCloud

In order to fix this annoying issue ensure your ISO images have the .iso extension **before uploading**. vCloud 5.1 and lower this was not an issue and vCloud automatically recognized the file type. Now we must tell it before the upload.
