window.cep.fs.makedir Fails With UNC Path on Windows

Hi all,

I develop InDesign CC Extensions.

I have used window.cep.fs.makedir() frequently with no problem. However, I was always using Windows paths ("c:\mydir\myfile.txt") - of course with "\" converted to "/".

For the first time, I have to deal with UNC paths ("\\myhost\myshare\mydir\). window.cep.fs.makedir is failing at creating new dirs with UNC paths (regular Windows paths work fine). writefile and readfile both work fine with UNC.

For example, window.cep.fs.makedir('//myhost/myshare/mydir/newdir') fails, even though '//myhost/myshare/mydir/' exists already.

Could someone please help me?

TIA,

mlavie
