I am wondering about Calibre's behavior regarding a full disk (0 MB free).
I have Windows 10, NTFS, 2.82 TB. The disk was filled with E-Books. To be concise: I was importing books when it reached full space and Calibre shot an error during the adding process and allowed me to view the debug code. I worry that Calibre may have written OPFs (metadata files) for more than 200+ E-books that were being added and overwritten some of the space that was being used by other programs on the disk. I didn't make any backups, if it did....it may have erased some files permanently.

TLDR

; I messed up with disk space management. It got full and now I am wondering if Calibre stops the creation of metadata files or if it continues regardless of the disk being full, in turn overwriting existing files by brute force on the disk.

I apologize if this was the wrong forum thread to post on, new user here.

Edit: Forgot to mention that the added books didn't mention anything existing under the "format" "tab". It was purely empty inside the Calibre interface. The title was there and the author was unknown (usual for me when I add books). But there was no mention of size.
