Previously I've Vista Home Basic. With that I used copy command so that copies 2 file as single file. But now I've Kubuntu 12.04. And I want to extract inner file. any help?
What kind of file is is? Is it ZIP, RAR, or 7Z? Try to right-click the file and select "Extract here" in Kubuntu. To create a single file out of multiple ones, copy those files to a folder, right-click the folder and select "Compress".
