Environment

• Windows version: Windows 10
• Processor architecture: AMD 5800X
• Dokany version: 2.0.5.1000
• Library type (Dokany/FUSE): both

Check List

• I checked my issue doesn't exist yet
• My issue is valid with mirror default sample and not specific to my user-mode driver implementation
• I can always reproduce the issue with the provided description below.
• I have updated Dokany to the latest version and have reboot my computer after.
• I tested one of the last snapshot from appveyor CI

Description

When the mount manager is activated, if the file cannot be put into the recycle bin, a deletion confirmation dialog is displayed. At this point, you haven't hit the delete button yet, but the file disappears from the explorer window. This phenomenon appears regardless of the dokany version. The same goes for Fuse. The actual file is not deleted and reappears when you refresh the explorer.

I ran mirror.exe as below.

mirror /o /r C:\Users\Raccoon\Desktop\Temp /l r:

A screen capture is attached.

Logs

Please attach in separate files: mirror output, library logs and kernel logs.
In case of BSOD, please attach minidump or dump analyze output.

Hi @onexzero ,

Thanks for the report.
What happens is that we get two FileDispositionInformation, one for deleting the file and the other one to undo the delete request right after.
The first one will notify the delete action to the system and make the file disappear here while the second one does not notify the file being back. Anyway, we just should notify on cleanup when the delete happens.
