Burning Files To cdr

I tried to drag a .txt file to the burn list, as suggested above, but it will not drop in. I get a message "+add to burn list" but I cannot get it to drop into the burn list. Is there another step I am missing?

 

Edge Search Does Not Permit Change of Region


I got these suggestions from the Microsoft Community forum.No. 1 worked for me:

Thank you for posting the query on Microsoft Community. I am glad to assist you on this.
We have reproduce the issue here and we are able to access non-regional search for google using Microsoft Edge.
I would suggest you to try the below steps and check if it helps.

Clear browsing data option of Microsoft Edge and check if you face the issue. To do so perform the steps below.

2. Select Settings and click on Choose what to clear.
3. Check the boxes Browsing history, Cookies and saved website data and Cached data and files and click on Clear.

Step 3:
It could also happen because of network issue. I suggest you to try with different network connection and check if it helps.

 

Uber file server build -- suggestions

Uber file server build -- suggestions?

I'm currently in the process of buying stuff for my file server build. Going to try and keep this build all in one thread this time.

Stuff already bought:

• 
  Motherboard (socket 1155 H61)
  RAM (1600MHz)
  PCI SATA cards
  Operating System (Windows 8 + FreeNAS)
  SSD
  CPU (35w Pentium Ivybridge 2.6GHz)

Looking for suggestions on:

• 
  GPU -- use the on-die GPU or buy a PCI-E graphics card (was thinking of a 7750)? My only requirement is that it is able to run 1080p mkv files and play Blurays without a problem.
  Case -- needs to hold as many 3.5" drives as humanly possible (more than 10 at least), while not being too expensive
  PSU -- needs to be able to run over 40 SATA HDDs as well as 6xPCI RAID cards and 1xPCI-E 2.0 RAID card. Silver, Gold or Platinum?
  CPU Cooler -- fanless or not?
  Case fans

That's all I can think of for now...unless I'm forgetting something...oh and one more thing -- I will be buying the hard drives two at a time as I run out of space. Also the PCI-E RAID card will be bought a lot later down the line, as I've only just got enough hard drives for 1 out of 6 of my PCI SATA cards.

Any suggestions, feel free to post. Thanks
