The rest is just the original filename padded with some random characters and possibly trunked to keep the length less than 32 characters. This is all internal to BASE and is not something that is visible to users or external programs. The system was designed to keep the number of files within a directory to a low number, both in the short timescale and in the long timescale. The reason is that we don't want to hit any hard limit regarding the max number of files/subdirectories per directory in the file system. The strategy may change if we discover some flaw. Also note that a file may be moved to a different place by BASE if it is modified (eg. replaced, edit, compressed, etc.). I don't see any point in using this system externally. It will be very hard to find your files. /Nicklas ------------------------------------------------------------------------ ------ Come build with us!
