The Renumber Tracks functions are used to renumber the track numbers of all files in the current selection.
The Per album variant ignores disc numbers. Every album will be renumbered from 1, based on the order of the track display. Remember that you can drag and drop files in the file list to set the display order.
The Per disc variant renumbers every disc in every album from 1, based on the order of the track display. An empty disc field or a disc field of 0 is considered to be 1.
The From... variant will prompt you for the first track number to use. Note that this function ignores albums and discs and simply modifies all selected files.
The above variants all number the tracks in the order they are currently displayed. The Random variant will number the selected tracks from 1 in a random order. This can be useful if you are making your own compilation and you want the tracks presented in a random order.
For each file the current Track Count value is retained. You can always recalculate the Track Count value by using an appropriate Track Count Calculation function or remove the information via the Clear function.
