Studio 2017 should really be able to support Flare "target" (.fltar) files as these always contain translatable content and our current workaround is to manually copy/paste translated content into these target files outside of Studio, however that's really time-consuming across 15 languages (soon to be 27). Madcap Lingo supports these and our company has considered moving to Madcap Lingo, just to save the amount of time that this takes.
