Update file linking method for Windows compatibility

[vncntprvst]

Modify file handling to use copy on Windows.
Tested and working - but then we get an extra copy of the original file. Also, no idea where the temp file is.
Could it be done in-place instead?

Thanks. It could be done in place, but you'd need to serve the parent directory. I opted not to do that because it could be a security risk. Wouldn't be too hard to make that an option... lmk if you want me to do that.

In the meantime, I'll merge this.

Thanks! I think it's ok to use copy, if serving the parent directory is a security risk. The copy is quite fast. The temp directory is written in the terminal, but maybe the location of the copy should be more explicit (it's in a view_nwb_<###> folder in C:\Users\<USERNAME>\AppData\Local\Temp)? Perhaps just add some info in the readme file?
