In projects involving large memories and several translators you may be asked to import/export .txt files into/from your Trados memory from time to time in order to update the memory with the latest changes to reflect the current status of the translation/editing process.
To import or export .txt files:
Open the respective Trados memory.
Select Import or Export from the File menu.
Then select the relevant options in the dialog boxes which appear on the screen. For details, see Trados Workbench Help.
