Getfileattributesex gets the file information in the inaccessible network path, which takes a long time.

For getfileattributesex to access the file information in the network path, if the network path does not exist or the network fails to be accessed, it will be a tragedy. This function takes a long time to return.

This function is fine if it is executed in the background. If it is to prevent normal use of users, or to prevent users from doing anything for a long time, it will be troublesome.

So try to put getfileattibutesex in another thread. The main thread can get an exit method. That is to say, if the user waits for too long, the user can exit the waiting process.
