SSD hard drive become 0 space left

I am using ADATA SU650 SSD hard drive and installed Windows 11 Pro 22H2(OS Build 22621.3007). It is working a few months already without any problem. Out of a sudden my SSD hard drive free space become 0 space. I usually check my hard disc space and found it was over 80 GB. free space. It is rather strange it could happen out of a sudden. I do not know what I am going to say about it. Any further things required please let me know. Thanks.

You could use Wiztree Portable to see if it tells you what is taking up the space. But sounds more like a SSD failure of some kind.

You could also run CrystalDiskInfo to see the current health of your SSD.

Download and run treesize to see where the space is being used: Find Space Hogs with TreeSize Free | JAM Software

Thanks thecaretaker and allan for the tips. When I used treesize I found out that Shield antivirus in the Quarantine folder it was so huge 126 GB. The other result of Crystaldiskinfo was 'Good'. How can I delete the quarantined files, I could see the files in treesize only but could not find the quarantine folder of Shield antivirus. I will be much appreciate for your help.

The video below shows you how to remove quarantined files from Shields Antivirus

Thanks fishingfool for the information but the video shown might not be the latest version, cause the interface is different from mine. As soon as it scan automatically it will show the items found and let you decide if you want to delete or not. What I wish to know where the folder which contain the quarantine items so I could see and deleted it.
