2.1.0.1000 on Windows 11 hangs Windows Explorer in single thread mode about dokany

Hi @dswiss-desktop-app ,

Thanks for the report but unfortunately this is a known issue (not exactly this case but expected)
https://github.com/dokan-dev/dokany/blob/master/dokan/dokan.h#L147

The usual scenario is that a new request B holds a lock on a file (asked by the system) while a request A tries to complete but it cannot as locking is required. B cannot execute because the thread is busy with A.
On a multiple thread mode, A would unlock when B would have been completed.

I highly suggest not to run in a single thread mode.

A workaround would be to have a pool of thread in the library that takes care of submitting the result to the kernel instead of the single thread. This will allow B to execute on the single thread while another thread is pending for A result submission to go through. This requires some work if anyone is interested to contribute I would be happy to review it.

Ok, we need to do a few changes to make our wrapper thread safe. But thanks for the explanation. Unfortunately our team has been downsized and we have no capacity to help you with this... ;-(
