The program you used may have mounted the drive as a network drive as a way of skirting MS security and tricking it. That said, be very careful with this sort of stuff that isn't native, a few years ago I was using one on a Mac (a well known program) and it corrupted the entire partition.
The easiest way to deal with all this is to add another partition that is ntfs or fat32 or another drive, but I hate doing this. Best advice I can give is do what I did a few years ago, if you are using multiple OS, build a cheap file server. It eliminates all the formatting issues, you can access your data even if your system is down (if you use a laptop), and you can offload large jobs that don''t need your input to it leaving your desktop free. Want to download a massive file while you game? No problem, let the server do it, need to compile something, let the server do it. Even if it takes longer, it's not tying you up.
It doesn't have to be anything special, you can build one from a Raspberry pi and a external drive, or whatever you have laying around. As an added bonus I can turn off my power hungry system at night (180watts idle, may be less now with new monitors) and let the energy efficient headless server (about 15 watts) stay running, it actually saves me money on electricity. Once you get used to having a setup like this it's hard to go back because it just makes managing your data and your desktop so much simpler. It's on a system no one uses so you have some virus security (especially if it's a different OS, hard to infect Linux from windows and vice versa), it's not under a high load so it's not under stress, and even if your desktop gets trashed, the bulk of your data is on another system and that system can perform backups regardless as to what you are doing. Oh and don't get a NAS, build a server from scraps. It's cheaper to build, cheaper to upgrade and it can do far more than a NAS.
