Can't drag and drop files (fbx, png, tga, wav) from File Browser to anywhere in Project Content Folder

Running 4.18.1 Windows 10 Enterprise 64 bit

It was working for a couple days. Then it stopped working. Seemed to stop working after exporting a Texture (had it saved to the desktop, which is different from default). 100% reproducible. Makes it seem as if the d&d functionality never existed.

I had been dragging and dropping assets with little to no problem 99% of the time on a different Windows 7 Enterprise 64 PC prior, so it’s not user error.

Edit:

  • Same issue occurs in a fresh Third Person Template.
  • Problem is still there after restarting the PC.
  • Just installed Windows 10 a few days ago on same PC.

I feel is a bug that persists from several versions ago, not sure if it’s the same I am experiencing (totally different computer and versions now), but when I drag and drop files, I have to drag the file over to the editor, wait for the cursor to change to a drop icon, but don’t release the mouse yet, let drop icon to disappear, and wait for the cursor to change again, and finally release the mouse button to make it work.

Installed UE4 on a fresh Windows 10 PC again and the problem hasn’t surfaced yet. Hopefully it doesn’t. I’m pretty sure it’s an editor bug caused by the export dialog. I remember, that while I had it up, I took focus off the Editor to check some other files and programs in File Explorer, Gimp. If I run into it again I’ll file a bug report.

I don’t feel like reinstalling the engine again so I won’t try to get repro steps.

Yeah, actually I’ve been dealing with that issue you’re talking about for maybe almost a year now. It’s really annoying right? Cause letting go during the first cursor nothing would happen.

The issue I was talking about here was that it would never changed to the cursor. It would be the crossed out icon from the beginning, the instant it’s over a d&d-able window in the editor. I could hold it over a drag-and-drop compatible window for a good 20 seconds or more and it would never change to a cursor.

Thanks for the info though. I’m glad to know it’s not just a prob with my setup.
