Thanks for the reply, some issues with the list:
It has several mime type for common extensions. For instance, for excel spreadsheets the supplied list has:
.xls
|
application/excel |
.xls |
application/vnd.ms-excel |
.xls |
application/x-excel |
.xls |
application/x-msexcel |
So, there is no guarantee that if we use a method to match to a list for multi upload that we will now match what was done through the single uploader.
I am going to try something now that could introduce a small margin of error possibility. Currently I check MIMe type, folder location, and file name to determine if a file is duplicate. I will remove MIME type checking so it is done ONLY on location and file name. Will report back if this does it for me.
