I checked hide files and folders in open/save file dilalog is no affect.
In the dialog of open/save file, can see the file of protected. if i use right key of mouse copy it and paste it to any folder still by the dialog, it will be successful.
how to solve? i need my exe program can open the file of protected, but I don't want the file to be copy and paste.

Hi, what version you are using?

7.6

I need my exe program can open the file and play it or view it by my exe program if the file is a video file or picture file.
But, I needn`t let the file to be copy and paste by the open file dialog.
