# Internals

Here is some information for people interested in QComicBook internals.

## Settings handling

QComicBook keeps settings in ~/.qcomicbook directory within these two files:

- qcomicbookrc - main configuration file
- bookmarks - bookmarks file

Both files are plain text files and may be edited manually (with caution!), if needed.

## Thumbnails handling

Thumbnails are stored (if thumbnails disk caching is enabled) in ~/.qcomicbook/cache directory.

## Archives handling

Archived comic books are decompressed to temporary directory (/tmp/qcomicbook-XXXXX, with XXXXX being some random number). This directory is purged when closing current comic book, opening a new one or quitting QComicBook.
