Putting this here so maybe to help someone else. Was having an issue installing an extension to my joomla install (Server 2012, IIS7) and kept getting time out in IE. Enabled error reporting and got ' -1 Copy failed.' A search thru google found a lot of people having the message but no real answers. The suggestions regarding setting permissions didn't apply as my settings currently in IIS are set wide open. After more searching stumbled on site where blogger showed how to get more info by modifying /libraries/joomla/filesystem/folder.php and adding $dfid to the error message (see lines around 104 and 142). I also added $sfid. Can't have too much info. What returned was an issue with windows thumbs.db file. I tried suggestions I found to disable thumbs with no luck. Finally found info on how to disable thumbs creation in gpedit.msc (instructions were for Svr2008 but worked just fine for Svr2012). Emptied the temp folder and then retried installing extension. Success!
