The manual in French is only speaking Functions, if I'm not mistaken and this is downright impressive. But it's really for programmers.

Translations are done by volunteers rather than the developer Kovid Goyal.

See ==>> calibre - Get Involved: Contributing translations to calibre. It's quite easy to make adjustments.

"Regular Expression" is a technical term used in Computing (English) with a specific meaning relating to searching of text. The literal meaning of the two words is best ignored, it is a 'label'. It could have been labelled as "Kleene filter", seeing as the inventor of the technique was Stephen Kleene.

Perhaps "Expression rationnelle" is used Computing (French) rather than a more literal translation such as "Expression régulière". You'd need to ask a French speaking Computing guru.

  What I wanted to get at the time and even today is reformatted names of files like this:

  [Author Name without spaces]_[Firstname without spaces]-[Name of the volume]-[N°]_[/total of volume]-[Title]-[Language] with the extension of the file (.epub, .mobi, .docx, …)

  I'll have to investigate why this is not possible for me. (And maybe also for others)

• You cannot change the names of the library folders and files (and that has always been so), see ==>> Want to change folder structure or file names in the Calibre library?
  
  You can control the structure and names of folders and files for the Send To Device and Save to Disk features, in the relevant Preferences dialogues, using ==>> [Tutorial] The calibre template language.
  
  There are some sample templates in this sticky thread in Library Management subforum ==>> Plugboard, template, and custom composite column recipes

  This is the place to report software bugs ==>> calibre - Bugs
  
  However, the French translation is maintained by MR Member Ptitprince. I suggest you take up your translation issues directly with him via a Private Message. BTW I discovered that by following the links from the the About\Contributors page at the main calibre site.

That's an MR forum issue not a calibre issue - you could do what I do when posting in French - write my post in English in an offline text editor (with spellcheck on), copy and paste it into Google's English->French Translator and post the results.
