Enum Constant Details

STAT

public static final FtpRemoteFileTemplate.ExistsMode STAT

Perform the STAT FTP command. Default.

NLST

public static final FtpRemoteFileTemplate.ExistsMode NLST

Perform the NLST FTP command. Used as default internally by framework components for files only operations.

NLST_AND_DIRS

public static final FtpRemoteFileTemplate.ExistsMode NLST_AND_DIRS

Perform the NLST FTP command and fall back to FTPClient.changeWorkingDirectory(String).

This technique is required when you want to check if a directory exists and the server does not support STAT - it requires 4 requests/replies.

If you are only checking for an existing file, NLST is preferred (unless STAT is supported).
