When you export folders or assets from the WorldServer Explorer, you can then translate them off-line. After you make changes, you import the assets back into WorldServer. This process is different from downloading and uploading assets.

This "ad hoc" process produces a translation kit (also called a project package) of segmented assets. An expiration date noted on the Create Translation Kit for Assets (Step 1 of 2) dialog tells you the earliest possible date that the segmentation data created in the process will be marked for deletion in the WorldServer database.
