I do appreciate that, but since we're on different planets where OSes are concerned, some things I do [easily!] on Linux may or may not be doable on windows. Let's toss around a few methods that should work.
1) There's always Airdroid, which
should work with any browser/OS. Install the
Android app on your phone. Then, on your computer, use a browser to go to the URL Airdroid shows you; it'll include your phone's IP address, and look something like: 192.168.1.101:8888
When you're first using it, you'll have to tweak its settings, for example, whether to allow the computer to connect to the phone without any input from you [on the phone]. Once it's set up, it's very simple to use; you'll see the contents of your phone in your browser, and have upload/download functions for exchanging files. I use this rarely, and mostly just for fun.
2) Some file managers have a service similar to Airdroid built in. In your file manager look for something like 'remote manager' or 'access from PC.' On your phone, you activate the service; like Airdroid, it'll tell you what URL to enter in your computer's browser. I'm not very familiar with these, but I think they only work one way, i.e., seeing the contents of your phone and downloading its files. I don't actually use these.
3) Using Dropbox or Google Drive is an option. From your computer, upload the fonts you want, then from your phone, download them into the correct directory. I wouldn't use this method.
4) My go-to choice, and what I use throughout the day: networking. I've set up all my computers to be networked, giving full read and write access to all the other devices on the same network [with correct account credentials]. So I access their files as if they're local. All of the apps I use, such as image editors, photo galleries, file managers, etc., can up- or download files, or entire directory structures, easily. This is what I recommend.
