Winrar command line compression ratio
1
I have a Winrar command line that look like this:
"c:Program FilesWinRARWinRAR.exe" a -afrar -s -m5 "e:output.rar" "e:foldertozip"
The folder that I am compress by default is 9.08MB. The compression file output is 7.62MB. But if I try to right click the folder and select Add to "foldertozip.rar", the compressed file size is 1.35MB.
How can I achieve that high compression ratio with command line?

Strange. Try to search where is the different behaviour cause. Some obvious specification: Do the 2 rar archive include the same files inside? (this because eventual setting to avoid hidden files/directories). If you compress again the 7.62 MB file renaming it and using the right click, will it shrink to something close to 1.35? Did you try to avoid the-sswitch or the-m5? Good hunting.

@Hastur Yes, I tried to avoid both-sand-m5. Having-m5or not does nothing different. But without-s, the file size is a bit larger. That is 8.1MB. The strange thing is I only get 1.35MB when compress withAdd to "foldertozip.rar". If I chooseAdd to archive..., no matter how I set, the output is 7-8MB. What setting isAdd to "foldertozip.rar"using?

It should be possible to check it. Try to see in the option-settings and maybe in the advanced panel too. You can read the manual here: maybe it can be related with Dictionary size and Memory to use or less commonly with delta compression options in the command line default settings vs your actual profile GUI ones.
