``Volume-Name'' is the name of a disk. ``unused'' is a random number. It is not used in the current version. The particular ``dpi'' values indicate, in what resolutions fonts are to be found on the disk.
A short example: With ``FontDisk=222d.131.207'' it is defined, that a disk with name ``FontDisk:'' exists, which contains two directories. Firstly the directory ``FontDisk:131'' with the fonts of the resolution 131dpi, and secondly the directory ``FontDisk:207'', in which the stored fonts of resolution 207dpi are to be found.
One resolution can exist more than one time at that. The search path is from up to down and from left to right.
This configuration file has to be in the directory <#367#>TeX:pk<#367#> with the name <#368#>fontvols<#368#>.
