Does keeping multiple formats affect performance?

ficbot · 09-18-2010, 09:42 PM

On my old laptop, Calibre was very slow and I got into a habit of only keeping the mobi files in Calibre and backing up original epubs elsewhere. Now I am finding my backup system getting a little unwieldy and I have to reconvert everything multiple times when my mother comes over and wants stuff for her non-mobi Kobo. So I am thinking of just leaving everything in Calibre but I don't want to gum everything else up. Is there a performance downside to doing this? Will it run faster if I leave only one format per book in Calibre or will this not matter?

It shouldn't matter. And you should update, newer versions of calibre have various perfomance optimizations.

I just updated today. Thanks, Kovid. So I should be fine to just re-add all the originals and nothing bad will happen?

yes, even if it does slow down, you can delete them easily enough by clicking the arrow next to the remove books button. And if it does slow down, do let me know, as I would be interested.
