I am using 7-zip to split a large folder (>200 GB) into chunks of 4.7GB so that I can burn them onto a DVD. But for now, I am storing these chunks in an external hard disk which has ~300GB of space. There is also >200 GB in the the drive where the folder currently reside.

But when I ran the operation, it gives a "Not enough space on disk error", and even when I deal only with a subfolder (>40 GB) this still occurs.

How do I fix this?

This is because your 'chunks' are bigger than 4GB. Hard drives formatted to FAT32 can only hold files with a maximum individual file size of no more than 4GB (or abouts).

You should clear your hard disk and reformat it to NTFS, where the maximum filesize is in the region of Exabytes (way more than any hard drives available today. This should be able to stop the "Not enough space on disk error"

According to the author of 7-zip at the following link, there's a bug where dragging and dropping from the 7-zip window to Explorer can cause this. I don't know if it's been fixed in later versions, but I'm still seeing it in a circumstance where I can't test the later versions, so I thought I'd post it: https://sourceforge.net/p/sevenzip/discussion/45797/thread/21b7bbab/#5ac1

I got this issue when I dragged and dropped it into another drive's folder. I realized the program checks the metadata (namely the available space) of the wrong drive, and then says there isn't enough space. The solution for this particular instance of the problem is to move the file to the drive with enough space before extraction.

Instead of dragging and dropping the file, I right clicked on the archive and chose to extract it that way. This worked for me.
