Limit the BITS Peercache size

This policy setting limits the maximum amount of disk space that can be used for the BITS Peercache, as a percentage of the total system disk size. BITS will add files to the Peercache and make those files available to peers until the cache content reaches the specified cache size. By default, BITS will use 1% of the total system disk for the peercache.

If you enable this setting, you can enter the percentage of disk space to be used for the BITS peercache. You can enter a value between 1% and 80%.

If you disable this setting or do not configure it, the default size of the BITS peercache is 1% of the total system disk size.

Note: This setting has no effect if the "Allow BITS Peercaching"setting is disabled or not configured.

Supported on: At least Windows Vista
