Windows paths use backspace when you use the code node js pathmodules

Without this line the depth is not correct on windows

[pankaj-arunsingh]

This is good windows path fix.

Perhaps fix the spacing:

if (process.platform === "win32") {
    fileDepth = relativeFileDir.split('\\').length;
} else {
    fileDepth = relativeFileDir.split('/').length;
}
