Zotfile is a Zotero plugin to manage your attachments: automatically rename, move, and attach PDFs (or other files) to Zotero items, sync PDFs from your Zotero library to your (mobile) PDF reader (e.g. an iPad, Android tablet, etc.) and extract annotations from PDF files.

Detailed information are available from the zotfile website.

The currently released version (3.x) is available here.

To install the development version on github:

1. download .zip file from github
2. extract .zip file
3. recreate .zip file containing all the files at the top level, i.e., install.rdf and the chrome directory need to be at the root of the .zip file and not under zotfile/
4. rename the file to .xpi
5. Install

• For zotero firefox: drag & drop on firefox
• For zotero standalone: In Zotero Standalone go to 'Tools->Add-ons->Tools for all Add-ons (the small, drop-down wheel menu next to the 'Search all Add-ons' box)->Install Add-on From File' and pick the .xpi file.

For Linux, Mac OS X or Cygwin users, there is a Makefile which takes care of creating the .xpi file. Simply run make instead of steps 3 and 4 above.

Zotfile can extracted annotations and highlighted text from many PDF files. But it will never be able to handle all files. If you can not copy & paste meaningful text from the file in your pdf viewer (open your pdf viewer (not the browser plugin), select text, copy and paste it somewhere), zotfile won't be able to extract the highlighted text either. If you can, there is a chance that future versions of zotfile will solve the problem. In general, these files depend on the pdf standards supported by pdf.js, which is the pdf library used by zotfile to extract annotations.

• Goto annotation in pdf

  This is not really a new feature but with two recent changes in Zotero (see this and this pull request), it became much more useful! Simply click on the link that is part of your extracted annotations, and zotfile will open the pdf on the page with the annotation. The feature now works on Windows as well (thanks to aurimasv) and I have added support for Skim on Mac. Check out the documentation for some more details.

• Improved extraction of annotation

  This version includes four improvements for the extraction of annotations. First, the new version greatly improves the detection of correct spaces between words. Second, the extraction is now based on the most recent pdf.js version (here is my fork with the modified version of pdf.js used in zotfile). With this update, zotfile should work with more pdfs. Second, the extraction is now about 40-60% faster (depending on the pdf) thanks to some improvements in the extraction code. Third, the extraction now runs in the background so that Zotero is not blocked while annotations are extracted.

• Get Table of Contents from PDF

  Similar to Mendeley, ZotFile can now get the table of contents from PDF and save it with links to the correct page in attachment notes. Simply click on the the desired section and zotfile opens the pdf on the correct page. Zotfile automatically extracts the table of content for all newly added pdf attachments (disable with zotfile.pdfOutline.getToc setting) or you can manually extract the toc using 'Manage Attachments->Get Table of Contents' (remove menu item with zotfile.pdfOutline.menuItem setting). This feature only works for pdfs that have an embedded table of content. Unfortunately, many don't.

• Support for sub-folders based on collection path (via wildcard %c) (thanks to simpzan)

• Tablet status is now shown in right-pane with other attachment information

  The right pane now includes a row with the current tablet status such as No for files that are not on the tablet or [Basefolder] for files that are in the tablet base-folder. Click on this information to change the tablet status and open or reveal the file on the tablet (very convenient because double-clicking on the attachment opens the imported zotero attachment and not the file on the tablet).

• Extract Annotation Color (thanks to RAG2ko)

  Zotfile now extracts the color of annotations. The color can be used in two ways: (a) To format extracted annotations: Just add some css styling to the hidden options for formatting. For example, change formatAnnotationHighlight to <p style="background-color:%(color);">"%(content)" (%(cite))</p>. The wildcard %(color) is replaced by the annotation color (you can also use %(color_category) for the color category---reddish is red etc). This styling has the same effect but looks a little better: <p><span style="background-color:%(color);">"%(content)"</span> (%(cite))</p> (b) To create separate notes for color categories: The hidden option pdfExtraction.colorNotes allows you to create a separate note for each color category (yellow, red, green etc annotations).

• Improved formatting of extracted annotations with hidden options (formatNoteTitle, formatAnnotationNote, formatAnnotationHighlight, formatAnnotationUnderline)

  The available wildcards are %(content) for the highlights text, %(cite) for the in-text citation of the zotero item, %(page) for the page of the annotation, %(uri) for the uri that open the pdf on the correct page, %(label) for the text label displayed in the title bar of the annotation pop-up commonly used for the user who added the annotation, and %(color)/%(color_category) for the annotation color as described above. The default for formatAnnotationHighlight is <p>"%(content)" (%(cite))</p>. WARNING: I removed the old settings. You will have to change the new settings if you want to customize the format of the note with extracted annotations.

• Improved default PDF reader detection on Windows (thanks to aurimasv)

• Hidden option pdfExtraction.replacements for custom, regular expression-based replacements in extracted annotations. This can be useful because some pdfs contain 'broken' characters. For example, [{"regex":" ?\u00f0", "replacement": " ("}] replaces the unicode character ð with ( to fix a problem in pdfs from a certain publisher. In this case, ð is a problem with the pdf and not with zotfile's extraction. The hidden option can be used to fix it.

• Information for attachments on the tablet is now hidden in the attachment note

• Improved information windows

• Improved renaming function (avoids re-indexing of linked attachments)

Other small fixes mainly for Italian translation, restriction of saved searches and renaming based on collections.

• Improved extraction of annotation

  The extraction of pdf annotations using pdf.js works much better now! Zotfile uses a modified version of the updated pdf.js library (here is the fork). The new version supports more pdf standards, detects spaces more precisely, sorts annotations in the correct order, and future updates to new versions of pdf.js are relatively easy. There are still pdfs that won't work though! Some pdf standards are not yet supported and if you can not copy & paste text from the pdf file using your pdf viewer (e.g. Preview), it's unlikely that zotfile can help.

• Goto annotation in pdf

  The extracted annotations now include a link that opens the pdf file on the corresponding page. For the extracted annotation "This is my text" (zotfile 2013: 4), zotfile 2013: 4 is a link that opens the pdf on the page with the annotation. Currently, this feature only works from reports (right-click on item and select generate report) but future version of Zotero might be able to open the links directly from the note (see discussion here and here)

• Tablet feature: Restrict saved search for tablet files to sub-folders

  You can now right-click on the two saved searches for tablet files and restrict them to one of your custom sub-folders. This is very helpful to quickly see the files that are in a specific sub-folder.

• Tablet feature: Support of colored tags in Zotero 4

  Zotfile now tags the parent item when an attachment is send to the tablet so that you can easily see which items are on the tablet. Simply assign colors to the two tablet tags (_tablet and _tablet_modified). But DO NOT manually add the tag to items or attachments (also not using the keys for colored tags).

• language improvements for French and German
• bug fix for subfolders based on wildcards

• enhanced renaming rules (thanks to Midnighter)

  1. Optional wild-cards: {-%y} only includes - if %y is defined.

  2. Exclusive wild-cards: %s|%j journal abbr. or if not defined full journal name.

  (for examples see below)

• additional wild-cards for author formating (author initials %I and lastnameF %F), pages (%f) and short title (%h)

• watch source folder for new files

  Whenever the focus changes to the item list in Zotero, Zotfile checks for new files in the source folder. If a new file was added to the folder, zotfile uses a clickable, non-disruptive window to ask the user whether s/he wants to attach that file to the currently selected Zotero item.

• revised auto rename with additional options

  Four options: Never, Always ask, Only ask if item has other atts, Always rename. The 'asking' uses a clickable, non-disruptive window that appears in the bottom right corner - same as previous info window but clickable.

• revised notifications and error handling

• Zotfile translation to German (thanks to wuffi) and French (thanks to gracile-fr)

• Allow periods as delimiter in filenames (thanks to jjatria)

• new option: "lower case" filenames (thanks to jjatria)

• new option: disable renaming so that attachments are only moved (hidden: .disable_renaming)

• new option: set opening and closing quotation mark for extracted annotations (hidden: .openingQuotationMarks, .closingQuotationMarks)

• new option: remove periods from filenames (hidden: removePeriods)

• bug fix: download of poppler tool was broken

• bug fix: preview of renaming rules for Unix and Windows

• bug fix: sending to and getting from tablet deleted note content

Examples for enhanced renaming rules %j - journal; %s - journal abbreviation

{%a}{-%y}{-%j (%s)} - author-2001-Proceedings of the National Academy of Sciences (PNAS) (if either %j or %s is empty, author-2001)

{%a-}{%y-}{%s|%j} - author-2001-PNAS or author-2001-Proceedings... if %s is empty
