%%Ais used when you use a batch program (*.bat)
%%A使用批处理程序时使用 (*.bat)
try remove one '%'
尝试删除一个 '%'
回答by aross
If you are doing it from the command line, you don't have to escape the %, so %ais sufficient. You only need to use %%afrom batch files.
如果您是从命令行执行此操作，则不必转义 %，这样%a就足够了。您只需%%a要从批处理文件中使用。
Also, you wanna be selecting the files instead of executing "G:\Files Sample\zip\txt\*.txt" as a command, which is what the /fswitch does in combination with single quotes. The full command would be: for %A in ("G:\Files Sample\zip\txt\*.txt") do 7za -tzip "%A.zip" "%A"
此外，您希望选择文件而不是执行 "G:\Files Sample\zip\txt\*.txt" 作为命令，这是/fswitch 与单引号结合的作用。完整的命令是：for %A in ("G:\Files Sample\zip\txt\*.txt") do 7za -tzip "%A.zip" "%A"
