3. Files

3.1. Installation Directory

Installed files are placed differently on different platforms. On GNU/Linux, the program executable is installed in <prefix>/bin and data files are installed in <prefix>/share/qwinff. The <prefix> part depends on the packager, and the most common prefix is /usr. On Microsoft Windows, all files, including the executable file and data files, are placed in the installation directory you choose, and the default is C:\Program Files (x86)\QWinFF or C:\Program Files\QWinFF.

3.2. Data Files

The contents of the data directory are described as follows:

presets.xml

This file contains ffmpeg presets. See Presets for details about the preset file format.

constants.xml

This file contains some pre-defined values used by the program. It is read once on program startup. The function of each entry is documented using xml comments in the file. QWinFF won’t start if errors or incorrect values are detected in this files, so modify this file with care.

translations/

This directory contains translation files (*.qm) for the program. Translation files should be named as qwinff_<language-code>_<country-code>_.qm. For example, translation file for Chinese (Taiwan) should be named qwinff_zh_TW.qm.

*.dll

(Windows only) Dynamic libraries the program depends on.

tools/

(Windows only) This directory contains external tools used by the program, including ffmpeg.exe, ffprobe.exe, sox.exe and other supporting tools/libraries.

3.3. Settings File

Program settings are saved separately for each user. On GNU/Linux, the settings file is ~/.qwinff/qwinff.ini. The installed version on Windows saves the settings in .qwinff\qwinff.ini in the user’s home directory, while the portable version saves the settings in qwinff.ini in the program directory.
