Make sure to take note of version control when uploading files via the Embeddable Upload Widget. Currently, if two files with the same name are uploaded to the same folder via the embed widget, then Box will append a (1) to the second file’s name. For example “Acme.jpg” will be “Acme.jpg (1)” if you upload it a second time.
Many files can be previewed in Box, but not everything is supported. Use the following link to see the previous types that are currently available for preview in the browser: https://support.box.com/entries/20366111-what-file-extension-types-can-be-viewed-by-box-s-content-preview
