\subsection calibration_data Calibration Data
-Calibration files are stored in the user's home/application directory.
-They can easily be moved from machine to another by copying the "cal"
-directory. Re-running a calibration utility will replace the existing
-calibration file. The old calibration file will be renamed so it may be
-recovered by the user.
+By default, calibration files are stored in the user's home/application
+directory:
- **Linux:** `${HOME}/.uhd/cal/`
- **Windows:** `%APPDATA%\.uhd\cal\`
+If you would like to specify a custom directory, you can do so with the
+`$UHD_CONFIG_DIR` environment variable:
+
+- **Custom (any OS):** `${UHD_CONFIG_DIR}/.uhd/cal/`

\subsection ignore_cal_file Ignoring Calibration Files
At runtime, the user can choose to ignore a daughterboard's calibration file by adding "ignore-cal-file" to the arguments. With the UHD API, it can be done as follows:
