 ### Scan Threads
 
-Diskover uses threads for walking a directory tree, for example, if `maxthreads` in the Diskover config is set to `20`, up to `max 20` sub-directories under the index top path (top directory path/mount point/volume) can scan and index at once. This is important if you have a lot or very few sub-directories at level 1 in `/mnt/toppath`. If `/mnt/toppath` has only a single sub-directory at level 1, crawls will be slower since there will ever only be 1 thread running. To handle this, Diskover ([available for annual subscriptions only](https://diskoverdata.com/solutions/)) uses thread directory depth config setting `threaddirdepth` to start threads deeper than level 1.
