the first difference is that the storage location is different. The files downloaded by Quark will be stored in the user's device, while the files collected by Cloud will be stored in the user's Quark account. This means that even if you switch between devices, the files collected by Quark Cloud will always exist without being deleted or lost.

the second difference is that the usage scenarios are different. Quark download is more suitable for offline use of files, such as when you can't connect to the Internet or data network. The cloud collection is more suitable for the situation that files need to be synchronized and shared between different devices, or the situation that browsing records need to be saved when switching between different browser tabs or pages quickly.

the third difference is that file management is different. The files downloaded by Quark need to be managed on the local device, including manual deletion, moving and renaming. The files collected by the cloud can be managed in the Quark application interface, and users can browse, search, delete and move more conveniently.

the fourth difference is that the storage space is different. Because the files downloaded by Quark are stored in the local device, the storage space may be occupied. The files collected by the cloud are stored in the Quark account, so users can get more storage space by upgrading the Quark account or buying more cloud storage space.

please confirm, thank you.
