Dynamic compression and decompression of cve-rar

As shown in the following figure, the compression and decompression of .rar are implemented. The Code is as follows:

I read it again yesterday and found that if there are spaces in the path (such as: D:/program files/), the compression and decompression will be problematic, and it took me a long time, finally, I had to interview in cmd for half a day and found that double quotation marks can be added to the path with spaces. In the code, directory. createdirectory (PATH); then, Judge path and rarname. If there is space, add Path = "/" "+ path + "/"";

RAR parameters:

1. Compression commands
1. Compress temp.txt to temp.rar rar a temp.rar temp.txt
2. compress all files in the current directory to temp.rar rar a temp.rar *.*
3rd, compress all the files in the current directory and all their sub-directories to temp.rar A temp.rar *. *-R
4. compress all files in the current directory and all their sub-directories to temp.rar, and add the password 123rar A temp.rar *. *-r-p123

Ii. decompress the command
1. Extract temp.rar to the RAR e temp.rar C:/temprar E *. rar C:/TEMP directory (batch operations are supported)
2. Extract temp.rar to the C:/tempdirectory, and extract the directory structure and directory structure 1 in temp.rar.
