Is this a bug? Strange behaviour of Calibre v0.8.24
I downloaded and installed the latest version of Calibre 0.8.24 for Microsoft Windows 7 (English).
I launched the installed software and added an ebook. After reading it, I clicked "Remove books" (the one with the three green arrows) to remove it.
I noticed a new folder was created on my drive partition. It is named "Calibre v0.8.4" (without quotes). There is a sub-folder called "Library" (without quotes) which contains a file called "metadata.db" (without quotes) whose size is 126KB.
How do prevent Calibre v0.8.24 from creating the folder called Calibre v.0.8.4?
Thanks in advance for your help.
