Hi,
For IE10 , it changed the security policy and will not allow javascript to get the FullPath of the selected file .
for temp solution , please try this meta in page <head>
<meta http-equiv="X-UA-Compatible" content="IE=7" />
To let IE choose IE7 mode.
(For advanced upload tasks , we plan to make ActiveX for next Uploader4.0 version. But no release date planed yet.)
Regards,
Terry
