Check if file is created

I am new to testcomplete, and I cant find what Check function to use.

Everytime an order is made (within my company's software) it creates a new file with a different name.

I have specified where this file gets made, it will be put in an empty folder. (emptied everytime test is run)

Now all I want testcomplete to do is: Check if a file is within this folder.

I can't seem to find what function I can use for this, I could really use some help.

Edit: Just to clarify I just want to know if a file exists there, What is in the file is not important. (it does need to be an .XML file)
