The error "The system cannot find the file specified" is displayed

I tried with the code below:

//responsible for reading . properties files
Properties prop = new Properties ()
def path = "D:\\SOAPUI\\Files\\application.properties"
FileInputStream fs = new FileInputStream(path)
//def inputFile = new File(path)
prop.load(fs)
log.info prop.getProperty("adminUsername")
log.info prop.getProperty("type")

--> The error is displayed

java.io.FileNotFoundException: D:\SOAPUI\Files\application.properties (The system cannot find the file specified) error at line: 6

Please advise
