Answer Wiki:
Save File(SAVF) is a binary file type commonly used to Store Objects or Libraries.
File Transfer will be easier from one server to another server using SAVF.
This saves the binary file information directly to the storage tape.

AS Pradeep said,
The OS/400 save file is a special object on the AS/400 that can be used to preserve other OS/400 objects for archival purposes and/or for transfer to another AS/400.
Because of the nature of an object- oriented system where commands are designed to work with, and only with, objects of certain types.
Surey…
what is the importance of it while tapeing ?
A “savefile” is a special type of file that can receive the output from a save operation (a ‘backup’ operation). It can also provide the input for a restore operation (a ‘recovery’ operation).
A savefile can be used in place of a device. If your tape (or optical) drive is unavailable, for example, you can save to a savefile instead. When the drive becomes available, the savefile can be copied to tape with the SAVSAVFDTA command. The tape will look like it was directly saved to.
You might have multiple save jobs running at the same time. Only one can use a single tape drive. By using savefiles, all saves can run concurrently and the savefiles can be tranferred to tape whenever the drive is available.
Savefiles can also be transferred across networks like a binary data file. That means that FTP or other transfer methods can send them to other AS/400s to be restored or to network servers for archiving.
A potentially big downside to savefiles is that they take up space on a system. Saving directly to tape doesn’t require using disk to hold the saved data.
