Problem

I recently downloaded a large number of GIS data files from a government agency to a file server and need to unzip all of them via the command line. However, is returning "Unsupported compression method 14". What does this mean? How can I extract the files?

Error Output

unzip filename.zip

Fix for: Unzip returns "Unsupported compression method 14"

Low Risk

These files were compressed using the LZMA algorithm (possibly using WinZip). LZMA archives are not supported by the command. I found that I could extract these files using 7z instead, as follows: Install p7zip (from source or package manager)
