Block USB read only

Dear all,

I am trying to find a way how to block USB, but only read from USB. To be more specific, I want to allow copy from computer to USB, but deny copy from USB to computer.

Is there any way how to do it with Microsoft tools or free programs?

Thank you in advance

If you're using a Pro copy of Windows 10 you can enable GPOs to prevent write or all access to USB devices. This is meant to block users from taking data off of company computers. There is no free program to allow the amount of control you are asking for. What you're asking for would require creating some file system filter drivers.
