Deleting Temporary Files

My game is tiny, size wise but my project folder just grows in size all the time.

I’ve worked out I can delete everything in the saved subfolder except config (deleting that resets all the UI changes I’ve made etc) and it saved me 900mb

I know size isn’t that much of an issue these days, but I rar my directory and upload to for backup.

I’d like to see a “delete temp files” menu option or something


Yeah I agree clean option will be cool

Not just cool, but totally farkin radical

This is even worse with the DerivedDataCache. That thing balloons to like 50GB across a week or two of work. And since UE4 defaults itself to my C drive, I’m racking up and deleting hundreds of GB of data from an SSD every month.

It does sort of feel like UE4 isn’t very fond of cleaning up after itself.

A small workaround for that can be found here: – Tutorials – UE4 Quick first tips

Hi rodstone,

This is a great idea! We will take it into consideration.

Appreciate it!

Because I manually RAR and backup my own game folder this makes a big difference to me!

you can use a .bat to rar while this feature coming.

"C:\Program Files (x86)\WinRAR\Rar.exe" a ../Backup.rar XXXXX.Uproject config content
