Using winrar to extract zipped files through the command line

  • I have an SSIS package that is going to be extracting zipped files, so my question is does anyone know how to extract a zipped file with winrar using the command line? I am able to do this with rar files, but when I when I try to do it with zipped files I get a message that the file is not a winrar archived file. I tried using winzip but I have the trial version so everytime the command gets executed in SSIS the registration screen pops up and now I have to manually enter the location of where I want to extract the data to.

  • I haven't worked with WinRAR, but I've done quite a bit of work with WinZip to automate zipping and unzipping files with SSIS. With the latter, the command line functionality is actually contained in a different executable, so you may need to call a different .exe file than you would normally use for interactive zip and unzip operations. The documentation for WinRAR should be helpful to find out exactly how to do this.

  • try using 7-zip, they have a cmd line version 7za.exe that comes with the download, which is free to distribute (no $ amt for it). It works great, I use it from my SSIS packages all the time.

  • Just use execute process task. Open Process, then in executable make path to winrar.exe.

    In arguments make path to zip file. (for ex. -e c:\temp\file_name.zip).

    In working directory make c:\temp

    Or, you can user unrar.exe and batch file.

  • I went with 7-zip because I couldn't get find the command line executable for winzip so the evaluation screen wont pop up (I tried all .exe files in the winzip folder) and winrar like I mentioned in my post wouldn't extract the files because its not a winrar archive. I would like to give everyone my gratitude for their help.

  • so far i have found this thread extremely informative. i will look at 7z as i have recently downloaded 7za.exe to use with my script ftp software. i will post up the results once i have tested a few things. thanks again for the info

    Yes - using 7zip is very much convenient it's not only free and saves $$ - it supports large number of archive extensions and have some cool compression methodologies to create a super-compressed file...
