OmegaT's internal translation memory format is not visible to the user, but every time it autosaves the translation project, all new or updated translation units are automatically exported and added to three external TMX memories: a native OmegaT TMX, a level 1 TMX and a level 2 TMX.
OmegaT的内部翻译记忆格式对用户不可见，但每次它自动保存翻译项目时，会自动把所有新增和更新的翻译单元都导出并添加到三个外部的TMX翻译记忆：一个原生的OmegaT TMX、一个级别1的TMX以及一个级别2的TMX。
