Massive Issues with Moving Files
This has been a problem since Beta and seems to still be a prominent issue in the Unreal Engine 4:
Moving Files from one folder to another internally using Unreal Engine 4 takes an enormous amount of time!
Why is this?? This seems to have been a consistent problem since forever in the Unreal Engine. My computer, running Windows 10, can move the same files in less than a second. Unreal Engine crashes after having tried to move a couple folders and the content inside for about 15-20 minutes.
My computer alarms me, saying that UE4 is using a huge amount of RAM and perhaps I should shut it down. Then I say "Cancel" to that and the engine is still running, slaving along as it tries to move files. Then suddenly, the engine crashes and both of my screens starts turning on and off several times, before the focus comes back on and several programs have crashed, most likely due to RAM issues.
Only UE4 does this. No other program on my computer does this AT ALL. To give you an example of what I tried to move, I went and made a new blueprint project with UE 4.14. Just the FPS template. Then I went ahead and added your kite demo assets to the project (which is 4.13 but there should be no issues otherwise I assumed). Then when the files were added, I wanted to adapt what was added to my own file structure and that included moving everything in the Environment Folder into another folder that I made.
Trying to make UE4 do this, will make the engine crash after attempting to move the files for about 15-20 minutes.
I repeat this has been a problem since day one of this iteration of the engine. Some needs to take a serious look at how UE4 relocates files and references because it's not working out.
Please make it your mission to look into this because it's getting silly at this point :/

Sorry to hear you are having issues when moving assets from folder to folder in the Content Browser. In order to examine this as a bug, however, we have to isolate a few factors that otherwise produce a false positive for a bug.
For example, in your sample you are using the UE 4.13 Kite Demo assets in UE 4.14, assuming there would not be a problem. This is not necessarily so; With each new iteration of the engine the fixes that are made are not necessarily backwards compatible with previous versions of the Engine. In short, in order to test this correctly you either need to have 4.13 Kite Demo assets open in 4.13 or 4.14 Kite Demo assets open in UE 4.14. Please test this way and let me know if you are experiencing a crash.
Also, be advised that the reason files do not simply move from one location to the next as easily as other programs is that UE4 is creating and leaving Redirectors in the original location. As it states in the documentation on Redirectors,
These two issues, coupled with the fact that the Kite Demo is our most massive and intensive sample with all the assets redirecting new reference locations, etc. it is not surprising to see a crash on a single system when the demo itself was built across multiple machines using a sophisticated file management system across a network.
All that said, if still feel there is a bug present, please recreate the bug in one of the Starter templates using the provided starter content, list your repro steps and, if we can reproduce the issue on this end, we will enter a bug report to ensure the issue receives appropriate attention.

Can't you put the Redirectors in a single file in the root directory to reference where everything is? When you move something it will just have to change its location in that one folder? Even if a redirector contains a lot of info you could still contain that in one folder!
I hate having empty folders all over the place, I make a lot of changes to my folders because of the type of project I have. It should be faster too.
