// Upload synchronization modes:
// mode=0: Upload all files
// mode=1: Upload all files that do not exist on the FTP server.
// mode=2: Upload newer or non-existant files.
// mode=3: Upload only newer files.  If a file does not already exist on the FTP server, it is not uploaded.
// mode=4: transfer missing files or files with size differences.
// mode=5: same as mode 4, but also newer files.

// Additional files and directores can be excluded by setting the SyncMustNotMatch property.
// The SyncMustNotMatch patterns apply only to the final filename or directory part of a path.
// If a directory matches, then it will not be traversed in a recursive traversal.
// 
loScp.SyncMustNotMatch = "*.o;*.obj;*.log; temp"

// The SyncMustMatch property can be set to restrict the files uploaded to only those
// matching at least one pattern in a set.

// Do the recursive sync to upload newer or non-existant files:
llBRecurse = .T.

// file uploaded.
