这是 3.71 版的 RAR 退出码说明，不知你用的 RAR 是多少版本，估计应该差不多
Exit values
~~~~~~~~~~~
RAR exits with a zero code (0) in case of successful operation. The exit
code of non-zero means the operation was cancelled due to an error:
255 USER BREAK User stopped the process
9 CREATE ERROR Create file error
8 MEMORY ERROR Not enough memory for operation
7 USER ERROR Command line option error
6 OPEN ERROR Open file error
5 WRITE ERROR Write to disk error
4 LOCKED ARCHIVE Attempt to modify an archive previously locked
by the 'k' command
3 CRC ERROR A CRC error occurred when unpacking
2 FATAL ERROR A fatal error occurred
1 WARNING Non fatal error(s) occurred
0 SUCCESS Successful operation
你看一下你 RAR 目录中有没有 RAR.TXT 或 .DOC 这个文件。
