Explorer - "New Text Document" issue #1003

Hello,
I'm having an issue with creating files in Explorer using, for example, the New > Text Document context menu. The issue is that Explorer creates the file ("New Text Document.txt") but doesn't seem to "know" that it has been created successfully. It therefore attempts to create it again but finds that "New Text Document.txt" exists, and so it creates "New Text Document (2).txt", then ... (3).txt, until I close the Explorer window. Closing the window briefly locks up Explorer so it restarts.

Below is my debugging output. Inside the [ ] brackets is the thread number in parentheses (xxx). The -1073741826 return from fs_lookup is simply "file not found". Everything seems to be normal, but after creating the file successfully, Windows/Dokan issues two GetFileInformation requests in different threads, then apparently concludes that the file hasn't been created and repeats the process.

I'm on Windows 10 Pro 21H1 x64.

Has anyone experienced a similar problem?

Thanks,
Sam S.

Hi @SSampson ,

Have you looked if GetFileInfo data returned are the correct one ? (Compare with mirror or memfs samples)
Maybe explorer is getting something that is unexpected and trying to create a new file to solve the issue.

Procmon might be more helpful while debugging such issues.

Hi @Liryna ,
Thanks for responding. I am porting this project from Dokan 0.6.0, so GetFileInfo was different. However, I had adapted it to return more info. But I do believe that GetFileInfo is the likely problem so I'll continue to investigate and compare to the samples.

Thanks for the tip on Procmon, I will use it as well.
