Hello @Jojo Tang , I test Cloud Mirror sample, the file is not downloaded automatically when right click. What's your Windows version?

Thanks for your confirmation. I test CloudMirror on Windows 10 1909 but it doesn't reproduce this issue. Could you have a double check to see if the CloudMirror can reproudce this issue?

And I see there seems a "Qsync" context menu when you right click on a file. Could you check whether this issue is third-party software related?

Hi RitaHan,
I removed third party, but the issue still existed (both OneDrive and CloudMirror)

Here provide video below:

Thanks. I see the issue on your side. It seems right click cause the file to be read but not open it. Since I can't reproduce this issue on both version 1909 and 20H2, it maybe an environment related issue. To confirm this, you may test other machines or set up a new, clean Windows machine to see if it reproduces the same issue.

Probably because some third-party context menu handler is trying to read the file when you right click it, thus triggering the download.

How can i check which app trigger this action or how to prevent this download action??

In
OnFetchData
callback, the
callbackInfo->ProcessInfo->ImagePath
will give you the full path of the app that triggers the download, see:
https://github.com/microsoft/Windows-classic-samples/blob/master/Samples/CloudMirror/CloudMirror/FileCopierWithProgress.cpp#L279

In
OnFetchData
, set
CF_OPERATION_PARAMETERS.TransferData.CompletionStatus
to a non-success status like
STATUS_UNSUCCESSFUL
will prevent the download, see:
https://github.com/microsoft/Windows-classic-samples/blob/master/Samples/CloudMirror/CloudMirror/FileCopierWithProgress.cpp#L84
