You can also find this information in the user manual integrated in Paperwork. It may give you information more specific to the version of Paperwork you are using.

workdir|rootdir = ~/papers

Global organisation

In the work directory, you have folders, one per document.

The folder names are (usually) the scan/import date of the documents: YYYYMMDD\_hhmm\_ss[\_<idx>]. The suffix 'idx' is optional and is just a number added in case of name collision. idx can be a string too.

Here is an example a work directory organization:

$ find ~/papers
/home/jflesch/papers
/home/jflesch/papers/20130505_1518_00
/home/jflesch/papers/20130505_1518_00/paper.1.jpg

Document files

Image documents

• paper.<X>.jpg: A page in JPG format (X starts at 1). It's the original page (as scanned or imported).
• paper.<X>.edited.jpg (optional): The page after post-processing and editing. (Paperwork >= 2.0 only)
• paper.<X>.words (optional): A hOCR file, containing all the words found on the page using the OCR (optional, but required for indexing ; can be regenerated with the options "Redo OCR (...)").
• paper.<X>.thumb.jpg (optional, generated and updated automatically): A thumbnail version of the page (faster to load). Starting with Paperwork 2.0, only paper.1.thumb.jpg is used.
• labels (optional): a text file containing the labels applied on this document (text + label color)
• extra.txt (optional): extra keywords added by the user

PDF documents

• doc.pdf: the document
• labels (optional): a text file containing the labels applied on this document
• extra.txt (optional): extra keywords added by the user
• paper.<X>.words (optional): A hOCR file, containing all the words found on the page using the OCR. Some PDF contains crap instead of the real text, so running the OCR on them can sometimes be useful.
• paper.<X>.edited.jpg (optional): The page after editing. (Paperwork >= 2.0 only)
• page_map.csv (optional): Created if the user move the page inside the PDF file. doc.pdf is not actually modified, only this mapping file. Pages are reordered on-the-fly when the document is displayed or exported. (Paperwork >= 2.0 only)

File details

hOCR files

With Tesseract, the hOCR file can be obtained with following command:

tesseract paper.<X>.jpg paper.<X> -l <lang> hocr && mv paper.<X>.html paper.<X>.words

For example:

tesseract paper.1.jpg paper.1 -l fra hocr && mv paper.1.html paper.1.words

Label files

Here is an example of content of a label file:

facture,#0000b1588c61
logement,#f6b6ffff0000

It's always [label],[color]. For a same label, the color should always be the same. Commas cannot be used in label names.

Page mapping

CSV headers are actually ignored by Paperwork.

Leep in mind that internally in Paperwork, all page numbers start at index 0. While the file names starts at index 1 (paper.1.jpg), the content of the CSV starts at 0.

Examples of page_map.csv below.

User has swapped page 3 and 4 in the PDF file

original_page_idx,target_page_idx
3,4
4,3

Page 3 of the PDF has been deleted by the user

original_page_idx,target_page_idx
3,-1
4,3
5,4

a JPEG page has been inserted in the middle of the PDF file as page 3

The JPEG page has the file name paper.4.jpg. If pushes all the pages of the PDF file further.

original_page_idx,target_page_idx
3,4
4,5
5,6
