Save to disk generate wrong filename

abuck · 10-13-2013, 10:34 PM

I have a bug where the save to disk feature generate a A.pdf instead my filename template

How to reproduce:
set a pdf book with the following metada:
Ids: isbn:9780596517359, amazon:0596517351
Date: 09 Oct 2013
Published oct 2008
Publisher: Adobe Developer Library
Languages: English
Title: The ActionScript 3.0 Quick Reference Guide For Developers and Designers Using Flash For Developers and Designers Using Flash CS4 Professional (Adobe Developer Library)
Authors: David Stiller & Rich Shupe

1- In the saving books to disk preference, set:
{author_sort}/{title}/{title} - {authors} - {publisher} - {isbn} - {pubdate}

2- Save to disk

You'll see that the generated pdf filename will be A.pdf which is not what expected.

It seems that the title caused issue (especially around the dot) because if you rename the title to:
The ActionScript 3 0 Quick Reference Guide For Developers and Designers Using Flash For Developers and Designers Using Flash CS4 Professional (Adobe Developer Library)

it will generate the proper filename:
ActionScript 3 0 Quick Reference Guide For Developers and Designers r & Rich Shupe - Adobe Developer Library - 9780596517359 - Oct, 2008.pdf

Not sure it is related to this issue but getting another weird behaviour:

Title: Cyber Security Policy Guidebook
Authors: Jennifer L. Bayuk & Jason Healey & Paul Rohmeyer & Marcus Sachs & Jeffrey Schmidt & Joseph Weiss
Ids: isbn:9781118027806, amazon:1118027809, google:E08UPzu42xoC
Date: 10 Oct 2013
Publisherd: Apr 2012
Publisher: Wiley

Output: Cyber ifer L. Bayuk & Jason Healey & Paul Rohmeyer & Marcus Sachs & Jeffrey Schmidt & Joseph Weiss - Wiley - 9781118027806 - Apr, 2012.pdf

as you can see, the title is croped out

Windows has a total path length of 256 characters. Trying to shove all your metadata into filenames on windows if going to leave you with problems. Stop relying on filenames for metadata, it is just not a tenable approach. Your filenames will be mangled to make the total path fit into that restriction.
