Sure. You don't have to uninstall the current version.

Yes.

Yes, you can group books by genre, however it in no way affects the way they are stored in your hard drive.

You can select a single genre and sort by author.

- You can combine steps 1) and 2) by doing CTRL-Q from the main Calibre Window.
- Step 3) is unecessary - simply install the new Calibre release over the old one.

Thanks for the answers. I did check the User Manual and the FAQ and found nothing about installing or updating that would answer those questions.

Kovidgoyal,
I noticed you said "not yet" for the hard drive structure (genre and/or alphabetical folder grouping) questions. Does this mean these things are on your "to do list"?

I'm asking because at the moment I'm looking to generate a fairly large path/tree structure, probably like this:
<Drive>:\eLibrary\<Subject>\<Genre>\<Alphanumeric>\<Author>\<Filenam e. ext>

The eLibrary is meant to be long-term data storage for multiple sets of data. Besides text-based data (fiction, RPGs, manuals, poetry, et al), I'm also going to include manga, music, images, movies, etc. I would prefer to use one structure through out. However, as I stated before, I have noticed that Windows can bog down when dealing with >500 children (folders or files) in a parent.

By using the path structure I outlined above, I'm hoping to avoid this problem. Each finer sort helps to keep the number of sub-folders within an acceptable response time. It might be better for me to consider a file server and/or NAS, but I'm just not that knownledgeable on networks... yet.

I'll have to go read another ebook.

kovidgoyal · 05-20-2009, 12:27 AM

yeah, it's on my todo list, but 500 is really riduculous. Windows really bogs down with only 500 entries in a node?

It depends. But yes, it can happen.

is this with ntfs only or fat32 as well?

Sabardeyn · 05-20-2009, 02:54 AM

I'm using WinXP SP3 with an AMD Athlon 64 x2 Dual Core processor 4200+ (2.21 Ghz) and 2Gb RAM on SATA 1 hard drive with a NTFS partition.

Windows Explorer is the most robust file management software to use as far as dealing with large numbers of children and system response time. Occasionally when issuing a File Open/Save command, response time will slow down. Other software is not as robust or can CTD from too many nodes.

I must admit I have a humongous library of material I'm storing. When I built this computer system I never imaging I would need so much data storage. But that was also before I was actively collecting some of this stuff.

(BTW, having nothing to do with calibre, I'm looking for any software that allows mass or batch file property changes. I need to add metadata [keywords, tags, authors, artists, dates, etc] to some of the non-book, non-music collections. PM me if you know of anything.)

Great program Kovid!

I was wondering, I have a jetBook that supports a hierarchical file structure in the form of AuthorLast, AuthorFirst>Title>FileName.Format

Exactly like Calibre saves files to disk. This format provides the best menu experience, and the only improvement I can think of would be to have a top level folder for genre, but since I tend to confine my reading to one or two genre it doesn’t matter to me.

The question I have is when I save to the removable drive that my jetBook presents to my Vista OS, it saves all of the formats that I have in the library, in my case ePub and PRC. Then I have to open each author folder and delete the unwanted file format. Also since the jetBook only supports USB 1.1, the time necessary to save several hundred books becomes significant, and if I have to save multiple copies it becomes even more unacceptable. Is there a way to specify to only save one format?

Thanks in advance!

kovidgoyal · 05-20-2009, 02:30 PM

There is a save single format option. Also, the 0.6 release of calibre should create a folder structure automatically when sending files to the jetbook via the send to device button.

emellaich · 05-20-2009, 04:22 PM

Regarding the Windows capability to handle multiple files per folder.

I haven't done testing in recent windows applications -- I think my work was way back in win 2000. However, at the time the problems was in Windows ability to do string math. Basically, file names were kept as characters and all the files in a directory were stored by the OS as one long string. As the size of the string became too large, file operations would really slow down. One thing to allow more files was to use shorter file names since this would shorten the total string size.

Also, I'm not sure of my recollection, but I believe the entire path was stored with each file name in the directory. Therefore, anything to make the path shorter (/n/f/r instead of /name/french/revolution) would speed things up considerably.

As I said, I'm not sure if these limitations still exist, but if you are seeing a slow down with the number of nodes then this is something that could be checked.

kovidgoyal · 05-20-2009, 04:28 PM

Interesting, thanks.

Sabardeyn · 05-21-2009, 04:16 AM

emellaich,

Thanks for the reminder. You are correct

. There does not appear to be any changes for later versions of Windows.

From Wikipedia:

Quote:

Although NTFS allows each path component (directory or filename) to be 255 characters long and paths up to about 32767 characters long, the Windows kernel only supports paths up to 259 characters long

movieking · 06-12-2009, 01:39 PM

Did a search but couldn't find anything, but I am sure the answer is here somewhere.

Let's say I import 50 books via calibre. I know that the files are also copied to the new folder that I specified in the setup. Now let's say I rename a few books, cleaning up tagging errors, etc. Where are the updated files that have been updated? The reason I ask is because I had to switch computers recently, and I took all of my updated books from the output folder after adding it to calibre, but none of the updated information was in the files, only the original names, authors, etc.

Where do I look for the files with the corrected information? I think that I looked in both the original and the destination folders but neither of them had the updated names.

itimpi · 06-12-2009, 02:13 PM

The files that you imported are (as you discovered) unchanged. The updates are held in the Calibre metadata database.

If you want the information in the files to be updated then you export them (Save to Disk) from Calibre. This information would also be updated as part of a "Send to Device" command or if you did a conversion.
