Description

Hi. I found a bug that file saving by Windows 11's notepad is not working on mounted drive. Notepad version is 11.2406.9.0. I checked that Windows 11's Notepad does not request write permission just before saving a file. Windows 10' s notepad requests write permission like GENERIC_WRITE before saving a file, so it works normally. Could I know is it bug?

Thank you.

Hi @cji80 ,

Could you explain how you did the test and share the logs of the sample that failed ?

I was able to reproduce the issue and looks like now it requires to use the mount manager option. It worked after using /o option with the mirror. https://github.com/dokan-dev/dokany/blob/7f25947970c1dc23cd3be9a0dbdb41f96e54f513/dokan/dokan.h#L97-L104

@Liryna Hi. After adding the DOKAN_OPTION_MOUNT_MANAGER option, file saving in Windows 11 Notepad proceeded normally. Thank you very much!!
