你好，请问extract是否是个程序，它的用法是怎样的
是的,用法如下:
EXTRACT cabinet
EXTRACT source
EXTRACT /C source destination
cabinet - Cabinet file (contains two or more files).
filename - Name of the file to extract from the cabinet.
Wild cards and multiple filenames (separated by
blanks) may be used.
source - Compressed file (a cabinet with only one file).
newname - New filename to give the extracted file.
If not supplied, the original name is used.
/A Process ALL cabinets. Follows cabinet chain
starting in first cabinet mentioned.
/C Copy source file to destination (to copy from DMF disks).
/D Display cabinet directory (use with filename to avoid extract).
/E Extract (use instead of *.* to extract all files).
/L dir Location to place extracted files (default is current directory).
/Y Do not prompt before overwriting an existing file.
