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"

Linux Engine Size


I have a small question. Why is the Engine on Linux so much bigger than on Windows? My 4.12 installation on Linux is ~30gb while my 4.12 installation on Windows is 8.2 GB.

Is this just at my machine or is it on every gnux system? And if it is the normal size, why is the difference so big?

Thanks in advance!


Product Version: UE 4.12

Because on gnux you have to compile the engine from scratch. All intermediate files of the compiling process are there. On Windows, the installation Version does not have those files.

Okay thanks!

Can I delete the intermediate files? Or is there any documentation which files are not needed? I just need to make some space on my HDD drive :D.

I used ncdu on the install directory to find what is taking the most space, a total of 26 GiB for me.

Because I did a full git clone, /.git is 7.1 GiB on my system. That could be deleted but would mean more bandwidth next update.

I tried deleting /Intermediate (6.8 GiB) and /Source (4.9 GiB), and the engine seemed to work fine but I ran into errors when trying to build projects.

You could save a gig by deleting Samples and Templates, but not much else is optional.

Is there a command like "make clean" to clean unused files for regular UE work?
