Hi Pseudo Kasiopee,
The favorites are the only stuff you loose ?
You loose them only after computer restart ? not after FileVoyager restart ?
The most common reasons why users loose their config is generally because they downloaded a Portable version and installed it in a protected folder (eg c:\Program files). By running in a protected folder, saving of settings is prevented.
The avoid this, install the “setup” version of FileVoyager. With those versions, settings are saved in AppData, which is not heavilly protected by Windows
