Swapping files is a common practice in Linux. It allows you to move or copy files between your computer and the network. Swapping files can be useful if you need to move some data between your computer and a remote server, for example. To swap a file in Linux, you first need to create a new file called Swapfile in the same directory as the original file. Then, you need to use the command Swapfile set to swap the contents of the old file into the new file. If you want to delete a Swapfile, you first need to remove its contents. Then, you can use the command Swapfile delete to delete the old file and its contents.
