I tried to change the product version, but each time, the size allocated to the HDD disk becomes too large to download until the end.

During the download process, a “lack of capacity” pops up and i can’t download. How can i download UE4?

My HDD file system is NTFS and available size 198 GB.

What do you mean? What is it these days? 30GB? That’s not a lot at all… You could skip content examples, that should shave off some of the bulk?

You mean the 200GB? You see this during download?

edit: if you go to the Properties of that drive, does it read FAT32 or NTFS?

If UE4 is just 30GB, i can download because it’s not big.

The disk allocated size of the folder where UE4 is downloaded is allocated larger than the actual file size.

So, during the download process, a “lack of capacity” pops up because of disk allocated size and i can’t download it.

plus : my drive reads NTFS

Not sure what could cause this then for an NTFS drive 😑

Bytes Per Cluster size might be big. I had same issue. you can check by opening Command Prompt as Administrator and type:

cmd

fsutil fsinfo ntfsinfo C: (which your unreal engine is loaded)

200 GO is NOT ENOUGH. I’m not kind to suggest high level setup but you need at least 1 TO and an SSD would be better. Unreal alone may take more than 60GO (It completely depend the version) just with a couple of free Stuff on the marketplace. You can reach the 200Go within a Week. So you will need more.
