You are correct, under the standard ConnectKey Scan templates the option is available. It appears as though the XAS Scan Apps use a static scan template instead of using the device's default File Format File Options and Filing Policy. The XAS App does not have the these additonal settings embeddend in the File Format Scan setting.
We suport .TIF File Format not .MTIF. You can set the default File format to .TIFF when you design the app or select the file format at runtime if the File Format Scan setting was configured to be shown in the app .
can mtif's be a choice in the ConnectKey Scan to folder app? The workflow application that is running on the server is looking for an mtif, PDF's will not work.
