问题
I'm developing a Windows Phone app (Windows Runtime, not Windows Phone Silverlight 8.1). In it, I have to let the user select multiple photos to do some processing with them. To accomplish this, I'm using the FileOpenPicker class, and it works fine. But I want to show only the pictures whose name doesn't start with a given string, for example, "abc-". So, in this case, I would only want the FileOpenPicker to display the pictures whose name doesn't start with " abc-". So, is it possible to do this? If it is not possible, how can I accomplish it? Thank you. (I'm launching the FileOpenPicker with
fileOpenPicker.PickMultipleFilesAndContinue();

No, it's not possible. You can filter only on the file type.
You can post or vote for feature requests on the Windows Dev Platform Feedback site.
