Can i include .exe and .dll files to my plugin?
I would like to know if I can include .exe and .dll files within my plugin.

Let me explain, I want to add to my plugin, AudioBook_Duration, support for reading .zip and .rar files, with .zip everything goes great with python libraries but with .rar I need an .exe and .dll for windows to run the unrarTool , on linux and mac it can be installed by console.

Can I include these .exe and .dll files to decompress them and use them in a transparent way for the user, or should I attach them separately so that the user can add them or not?

I do not know if I explain myself, if there is no problem I will add them, as it is easier for the Windows user.

Not a programmer, but Calibre already unpacks RAR formated books.
It might be available to you

The wrapper documentation is here.
If you want to use your own wrapper, unrar.dll is located in C:\Program Files\Calibre2\app\bin.

I saw the unrar.dll on app/bin folder but this folder is not the same for everyone, i'm sure there should be a variable for this path.

I'll search about it.

i whant to manage as many compresed files as i can but, custom libraries for each extension are a madness. (i saw about pyunpack and patool but i don't know how it work yet)

Thx both @theducks @Doitsu

Yes it is. Note, this is INSIDE the Calibre app folder, not the OS folder

calibre provides a Python API for RAR files. Using that inside your plugin avoids the need to worry about DLLs at all.

See calibre/utils/unrar.py
