Is it possible to make computer temporary storage?
MTP is the protocol in which the phone can transfer files from your phone to your computer (and vice versa). If it is a Windows computer, you should be able to plug your phone in and access and modify the files from the computer section in the file explorer. A pop up on your phone may ask you what protocol to use (for security reasons) and your phone's files can't be accessed until you select MTP. Macs don't support MTP (last I checked). You may also want to use a wifi file transfer app, if that is more convenient.
