DarkMX's config files are stored in a special folder, and keep track of the program state between sessions, such as the names of transfers, file hashes, file names, and miscellaneous settings.
On Windows 7 and newer systems, the config files for DarkMX are usually stored in:
C:\Users\MyUserName\AppData\Roaming\darkmx
And on older Windows systems, the location is usually:
C:\Documents and Settings\MyUserName\Application Data\darkmx
You may need to adjust your file explorer settings to view special or hidden folders because AppData is usually hidden by default.
On all Linux systems, the config directory is determined by following these steps in order:
If the command line flag
--user-data-dir=/path/to/dir is present, then that path will be used.
If the environment variable
DARKMX_USER_DATA_DIR is set, then that path will be used.
If the environment variable
DARKMX_CONFIG_HOME is set, then that path appended with
/darkmx will be used.
If the environment variable
XDG_CONFIG_HOME is set, then that path appended with
/darkmx will be used if it exists.
If the environment variable
XDG_CONFIG_HOME is not set, then
~/.config/darkmx will be used if it exists.
If the path
~/.darkmx exists, then it will be used.
If the environment variable
XDG_CONFIG_HOME is set, then that path appended with
/darkmx will be used.
And finally, the ultimate default path is
~/.config/darkmx
