In Ubuntu, the Archive Manager (or file-roller) has make it easy for anyone to compress and zip up a file or folder, but if you have a large file, say 20Gb, and you want to back it up to the CD/DVD, you will find that no amount of compression can you reduce the file size to fit into 1 CD/DVD. In such case, it is a better solution to compress and split the large file into several smaller files and store them separately. This also applies if you want to share a large file on a file-sharing site. Splitting the compressed file into several smaller files will make it easier for others to download.
Let’s say that the large file is a movie file found in “/home/username/movie/large-file.avi” and you want to compress, split and store the smaller files at the folder “/home/username/movie/split-flies/”, this is what you type in the terminal:
(change the filepath to where you want to keep the split files)
You will now see several files appearing at the “split-files” folder, each with file size of 650MB and with filenames “large-files.tar.bz.00”, “large-files.tar.bz.01”, “large-files.tar.bz.02”, etc.
To recover and extract the split files, type
and you can get the original file back.
Do you know of any other ways to compress and split files in Ubuntu?
