Can offline download of Thunder only be saved for 7 days? Will the file be broken after 7 days? Just disappear?

Hello, landlord, if you save it for seven days, you can save it online for seven days. Offline downloading is just like a network disk. You can renew it within seven days after saving it, and you can download it again if it expires.

There are local files on the computer, which will not disappear and the files will not be damaged. You downloaded that. Offline download is actually similar to ordinary download, that is, multi-step offline download, regardless of him.

Copy to USB flash drive within 7 days. If it exists locally, there is no need to copy it. Isn't it on the local computer?
