timmmay: Homegroups seem useful. I created one, shared folders using check boxes (videos and documents, even though I don't use the windows folders), and shared a folder that actually has content using "share with". I put sample content in each folder.
There's a problem though. On the windows 8.1 machine it can see the home group, and it can see the shared folders done by checkbox, but it can't see the extra folder I shared. I've checked file permissions and they include a "homegroup" used with read permissions. The "video" folder shared with a checkbox can be seen by the 8.1 machine, but when I double click it just blinks and won't open the folder.
Google hasn't given me any ideas how to fix it so far. I've turned on IP6 (on both computers and the router, which works), I've put the computers on the same workground, I've run diagnostics, I've turned netbios on IP4 on. I can't share folders in any direction across a homegroup, but the 8.1 PC can use existing shared folders. Any suggestions guys?
To be fair - I have had this sort of problem as well - windows sharing seems a bit picky sometimes - probably just means I dont know what I am doing :-(
How about as a test on the windows 8.1 PC you try and open the share using an IP address.
Get the command shell up (windows key + R).
Enter \\x.x.x.x\sharename -and press enter - where x.x.x.x is the IP address of PC with the files you are sharing and sharename is the name you gave the share.
I find that works for me when nothing else does - I ended up with the PC at home that I share stuff from and I just made sure it has a static IP address so any links I create are always valid.
