FileSystemObject sees unexisting files!

[Martin Mrazek]

Hi,
I use FSO ActiveXObject to save file from IE. In JS like

function saveToFile(pathN, content){
var fso, ts;
var ForWrite = 2;

fso = new ActiveXObject("Scripting.FileSystemObject");
ts = fspenTextFile(pathN, ForWrite, true);
ts.Write(content);
ts.close();
if (!fso.FileExists(pathN)) {
alert("The file <"+pathN+"> cannot be created.");
} else {
alert("Successfully saved");
}
}


surprisingly if the pathN contains unexisting path and the file is not
created, the fso.FileExists(pathN) still returns true (the message
"Successfully saved" is written...).

What's wrong there ?

My first guess is that at some point you're specifying the value of
pathN as a string literal that contains single backslashes, such as:

"C:\myFolder\mySubfolder\myFile.txt"

Which would succeed in creating a file named
"myFoldermySubfoldermyFile.txt" in the current directory.

Either use forward slashes or double the backslashes.
