Controlled Folder Access: Repeated Warnings of Blocked Memory Access

[infeo]

Environment

• Windows version: 10 Pro N 1909
• Processor architecture: x64
• Dokany version: 1.3.1.1000
• Library type (Dokany/FUSE): Dokany

Check List

• [x] I checked my issue doesn't exist yet
• [x] My issue is valid with mirror default sample and not specific to my user-mode driver implementation
• [x] I can always reproduce the issue with the provided description below.
• [x] I have updated Dokany to the latest version and have reboot my computer after.
• [x] I tested one of the last snapshot from appveyor CI

Description

Windows 10 offers the user the feature Controlled Folder Access, which is an additional layer of security against ransom ware.

When mounting a directory watched by this feature with Dokany, the user gets repeatedly warnings about blocked memory acces. There seems no loss in functionality.

Is the reason for these warning known? Of course the regarding application using the Dokany library can be whitelisted, but this may point to some error in the library.

Logs

Will be added later.

Hi @infeo ,

Oh that's something I never tried 👍 thanks for the report! I do not have my env ready for now so it might take some time for me to look into it but I add it to my todo 😃

Just wanted to say +1, ran across this while running Cryptomator (see here)

@infeo I could only reproduce the issue when not mounting with the mount manager option. With the option there is no error. I imagine thats also you case?

Edit: OK that's not the case. I wonder if that's not just something from what the dokan dll is doing.

Well there is not much information at all and everything works correctly. It seems like it is possible to get more information of the message from the enterprise version. Does anyone has that?

The path in the small report we currently have is the dokan device created but what the linked with the blocked memory :(?
