Returns a boolean indicating whether the specified file exists on the target server. The filename for programs is case-insensitive, other file types are case-sensitive. For example, fileExists(“brutessh.exe”) will work fine, even though the actual program is named 'BruteSSH.exe'.

|
## Example
|
|
|
|
|
|
```js
|
|
// The function call will return true if the script named foo.js exists on the foodnstuff server, and false otherwise.
|
|
ns.fileExists("foo.js", "foodnstuff");
|
|
|
|
// The function call will return true if the current server contains the FTPCrack.exe program, and false otherwise.
|
|
ns.fileExists("ftpcrack.exe");
