Copy files from Server to Box

Hello Team,

Pipeline details:
I have created a pipeline to copy files from Linux server to box folder. For that I have used “File reader” and “Box write” snaps in sequence.

Issue is - Server location has multiple files and it is only copying a single file (the file which I am giving in File path of box write snap).
How can I copy multiple files in single whatever is present in server location ?
can I also use some condition to choose any specific files from server location ?

Thanks.

Any suggestions
