function checkDirExist(path)
{
try
{
return
fs.statSync(path).isDirectory();
}
catch
(e) {

if
(e.code
==
'ENOENT')
{ // no such
file or directory. File really does not exist
console.log("File
does not exist.");
return
false;
}

console.log("Exception
fs.statSync (" + path +
"): "
+ e);
throw
e;
// something else
went wrong, we don't have rights, ...
}
