hey
I have posted here my opinion about sharepoint and the multi-upload functionality http://www.sharepointusergroup.at/community/Grasel/Lists/Posts/ViewPost.aspx?ID=37. sorry the post is in german so I will translate you the important things:
The multi-upload functionality in sharepoint is - friendly said - horrible. so we developed a client-application (sharxx) where you can interact with sharepoint in a better and friendlier way. e.g. like you see in the screenshot you can drop one or more documents into sharxx and upload it with the attributes you specify (you can also specify to use for all files the same attributes). there are lots of more additional functionalities like:
-) upload mails with all mail-attributes from outlook with drag&drop
-) define your own navigation
-) offline functionality
-) define easily views
-) ...
If you are interested in more information (we are currenlty overworking our website) please don't hestiate to contact me office@sharxx.com. Of course the application is available in english.
