FAQs About Not Enough Disk Space But There Is Plenty

1. Why does my computer say there is not enough disk space when there is?

There could be some hidden or virtual memory files taking up space, and you need to delete the files on the virtual partition. It is also possible that you have a disk format limitation. If it is in FAT32 format, you cannot write files larger than 4GB. Bad sectors or non-contiguous sectors are also likely causing this. You can check the specific causes and solutions in this post.

2. Why is Windows 11 taking up so much space?

Because Windows 11 has higher upgrade requirements. So, you need more disk space to ensure the upgrade is successful. And some temporary files, system restore files, and junk files will take up space.

3. Why my hard disk is not showing full capacity?

If your drive is not showing full capacity, it may be because your external hard drive or firmware is outdated. You can use EaseUS Partition Master to convert your MBR to GPT or update your drive.
