C9: I tried to attach an Excel file, but it's not working.
Hello! Please help....
1. I have attached an excel file using the 'Open URL/File....' and it's pointing to a folder from my desktop.
2. I've published the project and I see the excel file as part of the published files (within the folder). 
3. I've moved the project folder to our web server, but when I click the project to see if I'm able to open the excel file, it doesn't open the excel file. It opens to a file that can't be understandable (see image).
