i installed extension on Linux from Flatpak

[Gawrion]

Extension didnt want to run. Problem was that outName = filePathOnly + '\\' + fileName was building invalid path begining with \/..... so i changed code a little bit to check if two begining characters of path are \/ and deleting first char if its true:

outName = filePathOnly + '\\' + fileName
if (outName.charAt(0) === "\\" && outName.charAt(1) === "\/") {
outName = outName.substring(1);
}

Now extension is working and i think it will work on Windows too. Just inform U about issue and how i resolved it simple. I made a fork and pull request. Test it on windows if that works...
