The dcelocal/var/adm/dfs/cache/Vn files, or V files, hold chunks of cached data on a client machine using a disk cache. In the name of an actual V file, n is an integer; each V file has a unique name (for example, V1, V2, and so on). The format of a V file depends on the information it contains.
By default, each V file holds up to 65,536 bytes (64 kilobytes) of data. The default size can be overridden with the dfsd command. Never directly modify or delete a V file; doing so can cause the kernel to panic.
