Hi, I'm running a qt node and I recently took it apart and noticed that the qt data folder was only 4-5 gigabytes and I previously remember that I used to have the whole blockchain, which is no above ~150GB.

I started the node and it had some blocks that it needed to download but other than than it seems 100% normal, so my question is why is it only 5GB? I should have the whole blockchain or do I but it's compressed?

Thanks in advance for any help!
