For example, pack all the East-West packages in E: \ WEB \ directory as 1.rar and put it in the E: \ WEB \ directory for download.
"C: \ Program Files \ WinRAR \ rar.exe" a-k-r-s-M1 E: \ WEB \ 1.rar E: \ WEB \
Parameter description:
A. Add the file to the compressed file.
-K: Lock the compressed file
-S Generates solid archives to increase the compression ratio.
-R includes subdirectories
-M1 sets the compression ratio.
-When you add M0 storage to a compressed file, the file is not compressed.
-M1: the fastest way to use (low compression)
-M2: Fast Compression
-Standard (default) compression mode for M3
-M4: better compression mode (better compression, but slow)
-M5 is best to use the maximum compression method (the best compression, but the slowest)
