Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Emptied .vs folder, unable to start ue4

I emptied the entire ".vs" folder and now I get this when trying to compile in Visual Studio 2017:

Unable to start program '[snip]\Engine\Intermediate\Build\Unused\UE4.exe'

None of these answers solved it for me: https://answers.unrealengine.com/questions/218266/unable-to-start-program-ue4exe-error.html

I know it's possible to delete the .vs folder in the project dir (I emptied it because it was 6GB in size). What I tried after emptying the .vs folder:

  • Delete the Binary folder

  • Delete the Intermediate folder

  • Delete the .suo file

  • Generate Visual Studio project files

  • Set my project as the startup project

I restored the .vs folder and it works again. But I rather have the option to clean it because this 'cache' folder is about 20x bigger than my entire project. I rather not have to backup/GIT this folder as well.

I moved the project to a directory without spaces in the path. Then I deleted EVERYTHING except the Config, Source and Content folders (also deleted the GIT files just to be safe). Then I generated the Visual Studio project files and it compiled.
