Ive built a rather nice library for myself using the marvelous Calibre (which I keep current with all updates) and have been adding books. I was up to around 134,000 various titles..many of which were job related (old mechanics books) and recently noticed that at some point when I added more books...some of my xx.epub files are gone...leaving only a file folder with a metadata.opf file in it..and the name of the book as a file folder name. What the dickens am I doing wrong? My book count is now down around 34,000 titles and when scrolling down the book directory from Calibre..it gives book and author..some commentary Ive made in the past but book size in megabytes is empty. When I go to that book location...I only find the meta-data.opf file..nothing else.
Some books are still there...but Im afraid they will be shuffled off somewhere before long...
Help!!!
