Does Kobo use more storage space than Sony
Hi
I recently purchased a Kobo Glo reader. I noticed, that after putting 165 books from my Kobo library on the device, that I only have approximately 323 MB available out of 1.32 GB. When I compare this to my Sony PRS-T1 Reader with the same number of books, the Sony reader shows that I have 1.02 GB available out of 1.4GB. Is this normal? Does the Kobo take so much more space per book than the Sony Reader? |

I have 800 titles on my Glo and I still have 400+MB available. There's something hinky going on in your Glo... I suggest opening the Glo's folders on your computer and start adding up the size of the folders. If it really adds up to 1 or so GB, just look for the biggest file. There might've been an error when the books were being copied. If the folders don't equal the displayed consumed storage on you Glo (and your computer displays the appropriate storage pie chart) then there might be a problem on your Glo's database. Just log out under account settings and log back in. You will loose all your reading progress, annotations, and reading life though. You could make a back-up using Calibre and the Kobo Utilities plug-in. And speaking of the plug-in, you can also check the integrity of your Glo's database using said plug-in. But I can assure you, unless your books are 10MB each, you won't run out of storage that fast...

Thanks. I decided to log out of Kobo on my ereader. It took me through the setup process again, and is now in the process of downloading my library. I opted for wireless setup this time, as opposed to connecting the reader to my PC as I had done initially. I wonder if this has anything to do with the fact that my Kobo library is comprised of quite a few books purchased from the Sony reader store site when they were around. I also find charging the Kobo Glo via the USB connection on my PC is very slow. Its been connected for several hours and shows only 54% charged. Is it possible to charge via an AC adapter? |

When you put a book on a Kobo device, the following files and other things are created:
From what I know about the Sony, it will have all the above, but, I think it uses less copies of the covers and the less database entries. Also, I don't know how big the cover images it has are. I would expect it to use less space for the same book, but not very much. |

A book in kepub format (either sideloaded by Calibre's KoboTouchExtended driver or synced from Kobo) takes up a lot more space than the same book sideloaded as a plain epub, both for the books themselves and in the database.

There are other things that consume storage space besides books though, I think the main one is the recommendations you get when you sync with Kobo. Each recommendation has a full set of cover images, and new ones seem to be added faster than the old ones are deleted, so after a while you can end up with a lot of them. |

On my Kobo Glo, I found a folder within the .kobo folder called "kepub" which contains 166 files and uses 709MB, almost double the space that the Sony Reader epub files use. |

From that I gather your books are in kepub format, synced direct from Kobo. If you sideloaded them to the Glo in epub format they would use a lot less space, probably similar to the Sony.

One possibility is that those are free previews downloaded from Kobo. |

So to be clear, if the books are in kepub format (either because they were synced from Kobo or sideloaded as kepubs) then the books themselves and their associated database entries will take up about twice as much space compared to the same books sideloaded as epubs. But either way, there could be a whole lot of stuff taking up space and database entries other than just the books. Last edited by GeoffR; 08-15-2014 at 09:03 AM. Reason: Are the books sideloaded or synced, epub or kepub? |
