index files exist in order to speed up drawing the audio/video tracks. This option determines where index files are placed on the disk
Size of index file
determines the size of an index file. Larger index sizes allow smaller files to be drawn faster, while slowing down the drawing of large files. Smaller index sizes allow large files to be drawn faster, while slowing down small files. The default is currently 4kB for average size files.
Number of index files to keep
to keep the index directory from becoming very large, old index files are deleted. This determines the maximum number of index files to keep in the directory.
