File name too long

talmage · 08-15-2013, 03:55 PM

What can I do about a PDF that has a very long author list embedded in it? Calibre 0.9.42 tries to import it and gives up with the following error:

calibre, version 0.9.42

See the Red?
Commas that should be & signs to separate the authors in the metadata so 'Brent' as 42 middle names

Perhaps the file will be added correctly if you disable reading metadata from inside the file? Worth a shot... Preferences, Add.

Disabling read metadata from file should work as from what I can see the author name is long enough to hit calibre 180 character directory limit.
Apart from that I would recommend keeping your calibre library in the root folder of your drive. Instead of where calibre makes it by default in your My documents folder.

That's not a calibre limit, that's a filesystem limit. Judging by the fact that the filenames are using forward slashes, you are on some unix like OS. Which means you have put your calibre library on some network filesystem or some external disk with a windows filesystem on it, dont do that. Move your calibre library to a OS native filesystem and your problems will go away.

Thanks to all of you for your advice. I disabled the reading of metadata during import. Then Calibre was able to import my PDF. I have no way to change the medata in the PDF.

Following kovidgoyal's suggestion, I looked into the maximum file name length for ext4, the filesystem I'm using on my Linux box. It's a local filesystem. The upper limit is 255 ASCII characters. However, my home directory is encrypted using eCryptfs and that has an upper limit of 143 ASCII characters. The file name as proposed by Calibre has 158 ASCII characters. Mystery solved!
