You can use “compress.exe filename -R” to automatically reanme the compressed files. This will be useful if you want to compress multiple files with single command. In this case you can’t specify the file names for all the compress ones so adding -R switch will automatically rename the compressed files.
If neither the output file name is specified nor -R switch is added then you will get an error like below.
