Double click one cloud file to fetch file but get two or more fetch data callback

Question

When working with the Cloud Filter API, double click "one" cloud file (icon_page_focus.ico) but app got more than one fetch callback and then download extra files

Original three cloud files

Then double click "icon_page_focus.ico" file, app got three fetch callback to download three files

Test with onedrive have the same problem.

I think the "similar file name" will be fetched at the same time.

Hello @Jojo Tang ,

I can reproduce this issue via double click on image file. Yes, same result with OneDrive and CloudMirror sample. However TXT files have no such issue.

But when you change the default app for Photo viewer from Microsoft.Photos to MSPaint, this issue will disppear.

So this seems related to Microsoft.Photos application's feature. It will preload the previous and the next image to the one you double click on, then you can click the < or > button to view them in less time. If you want to do further investigation, you can use ProcessMonitor to check the operations of the Microsoft.Photos application, you will find that two other image files are also read when you double click one image file.

Thank you!
