Why can't I rename a file?
It is normal if you cannot rename files within the "Inbox" folder, since it was embedded by Apple itself (and not created by us). If you want to rename the file, please move it from "Inbox" to other folder.
For instructions of how to move files between folders, please visit the link below:

Why can't I access my files through Wi-Fi connection?
While you transfer files through WiFi, please make sure your Device's screen remains at the WiFi page(as the image below):
Why can't I find PDF Reader on the open-in app list?
PDF Reader dose support the open-in feature.
Unfortunately Apple's device has a limitation on the app number displayed on the open-in list and we are not allowed to change its order.
We suggest you delete some of the existing apps equipped the open-in feature to get PDF Reader available on the open-in list.
Why can't I see anything when I access to the text reflow feature?
The text reflow feature can automatically detect text within a PDF file and display the content in text form. Your PDF file was probably converted from images and this kind of PDF doesn't include text at all.
What can I do if I forget the password of my private folder?
Please tell our Customer Service Department about your issue at appservice@kdanmobile.com and we will help you with what you've encountered ASAP.
Why can't I see what I filled in on the form?
It's probably because the PDF form's format cannot be properly recognized by the viewing engine. We suggest you send us the file to our Customer Service Department at appservice@kdanmobile.com and we will test the file for you.
