* It's best to acquire the file in its original format, such as one of the supported file types above (most commonly, InDesign or Microsoft Word), and translate that file.
** TMX files can be uploaded by managers with sufficient permissions using the Translation Memory Import flow.
Consult your Customer Success Manager about creating a custom upload template for any of the above file types. The custom upload template automatically applies specific directives of your choice to the file, upon upload to Smartling, saving you from having to manually apply the same directives to a certain file type.
