com.enterprisedt.net.ftp.RecursiveOperations

public class RecursiveOperations
extends java.lang.Object

Performs various recursive FTP operations. Some operations permit a wildcard string to be supplied for matching filenames (directories are not matched against the wildcard). The syntax used is '?' for single chars and '*' for multiple chars, e.g. 'asdf??df*abc' would match 'asdfxydfdsfsjfkj33abc'. On Windows clients, case is ignored.

Note that if there are a large number of files to be transferred, the client or server may run out of sockets, as a new socket is created for each data transfer and each directory listing. TCP's TIME_WAIT means that sockets are not reclaimed immediately. If sleeping is enabled via setSleepEnabled(true), then Thread.sleep() is called after n transfers, where n is set by setCountBeforeSleep(n). The time spent asleep is set via setSleepTime().
