The output from the previous command looks like this... We just wanted the list of files on the FTP server that end in ".vt"
C:\>for /f "tokens=8 usebackq" %f in (`ftp -s:dir.inp
ftp.arsc.edu ^| find ^".vt^"`) do @echo %f
AK_Cntr_Cltr_Img_ANC_FAI_D
LT_30M_59_
68N_141_15
3W.vt
ANWR_146_41W_71_69N.vt
JUNEAU.vt
Does this make sense and/or help?
