[arch-general] Can I attach Windows partition space with home without reinstalling?

[Junayeed Ahnaf via arch-general]

Hello,

So I have arch installed on a 50GB space, I also have 400 GB  as a 
windows partition, I want to know is there a way for me to delete that 
windows drives and attach them with either / or /home so that I can use 
them from Linux without reinstalling?

Thanks
