So I got a assets free demo assets and it came as executable ue5 files and I want to edit these files and add them to my own project. Any ideas on how can I do this? How can I copy blueprints and other stuff?
Hey @Bo1mirzo!
Did it come with .pak files? You can unpack those with the UNREALPAK.exe that comes with the engine! Anything that you are not allowed to unpack SHOULD be encrypted, but keep in mind copyright laws and make sure anything you redistribute is lawful. 
Hope that helps!

Hi @Mind-Brain, I found .pak, .ucas and .utoc files and extracted them through your help, thank you very much! and where should i import them so that i can use them in my project?

If they are usable files, drop them directly into “Content” while the project is open THROUGH UE5, don’t use Windows Explorer or Macintosh Finder for it as it can cause issues.
That being said I don’t know what you’ve extracted and the extensions for them, if you drop those here I might be able to tell you if they can drop directly in, or if you need to put them in another program first and re-export them as a different file type (For instance, sound works best as .wav).
The file is too big to put it here but here is the link for the demo FPSMC Demo.zip - Google Drive
I’m sorry, I have a policy not to download links from forums or other users on the internet unless I highly trust them. I also advise you do not do so either! Malware of all types spreads this way, especially on forums.
If you could just look at the file types you’re looking to move and type them out here I could be of more assistance! Things like .wav, .mp3, .fbx etc.
Hi! I want to move every file to edit, most of the files consists of .dll however there is .pak, .ucas and .utoc files. I unpacked them with the guide on the video you sent earlier btw thank you a lot for that 
. I unpacked .pak file and clicked on the unreal engine project and there was nothing.
I want to edit that project and make a game based on that, this is how it should look like
Can you provide the link to the website where you got the demo?
Sorry, not the google drive link, that’s where the file is hosted. I am asking for the website that the project is not hosted, but where it is featured. I’m looking for how you found the project itself, to see if there are some sort of additional instructions that might make more sense of how to help you!
If you want the content you need to pay for it.

I got you, here is a youtube video for it https://youtu.be/KKakevN35oc?si=OJxEGMxZ5ghX61FT and epic marketplace https://www.unrealengine.com/marketplace/en-US/product/fps-multiplayer-controller
there is no other way of extracting files through demo? only paid method?
Yeah it looks like the errors you’re seeing are the ones you get when you have tried to unpack an encrypted file. The assets are to be paid for, the demo is only for them to be seen. Otherwise it would just be a free pack. Long story short, there is no way to unpack them without doing so illegally and so I would suggest going another route.
