Parameter	Type	Description
files	string \| string\[\]	Filename or an array of filenames of script/literature files to copy. Note that if a file is located in a subdirectory, the filename must include the leading `/`.
destination	string	Hostname/IP of the destination server, which is the server to which the file will be copied.
source	string	_(Optional)_ Hostname/IP of the source server, which is the server from which the file will be copied. This argument is optional and if it’s omitted the source will be the current server.

**Returns:** boolean True if the file is successfully copied over and false otherwise. If the files argument is an array then this function will return false if any of the operations failed. ## Remarks RAM cost: 0.6 GB Copies a script or literature (.lit) file(s) to another server. The files argument can be either a string specifying a single file to copy, or an array of strings specifying multiple files to copy. ## Example 1 ```js //Copies foo.lit from the helios server to the home computer: ns.scp("foo.lit", "home", "helios" ); //Tries to copy three files from rothman-uni to home computer: const files = ["foo1.lit", "foo2.txt", "foo3.js"]; ns.scp(files, "home", "rothman-uni"); ``` ## Example 2 ```js const server = ns.args[0]; const files = ["hack.js", "weaken.js", "grow.js"]; ns.scp(files, server, "home"); ``` For darknet servers: The destination requires a session, but unlike [exec](./bitburner.ns.exec.md), does not require a direct connection — scp works at any distance. The source server has no darknet requirements (no session or connection needed). Use [dnet.authenticate](./bitburner.darknet.authenticate.md) (requires direct connection) or [dnet.connectToSession](./bitburner.darknet.connecttosession.md) (at any distance) to establish a session.
