Because screen-scraper internally uses Java it is important that file paths follow the requirements of Java. That is that file paths follow the Unix/Linux structure (e.g., /usr/local/file.txt). If you are working on a machine that follows these conventions then it will not look any different to you; however, if you are working on a Windows machine this is an important difference to keep in mind.
Windows uses the backslash (\) as a file delimiter but Java uses it as an escape character. That means that on a Windows machine you need to pay closer attention to file paths as they will look a little different.
Windows file paths should use either a forward slash (/) or two backslashes (\\) to delimit file paths.
