Sources with the BigML Dashboard
3.6 Compressed Formats
Users can save bandwidth and time by creating sources from compressed files. The files can be gzipped (.gz), compressed (.bz2), as well as zipped (.zip). BigML also supports compressed TAR archive files, such as .tar.gz, .tgz, .tar.bz2 and .tbz2.
When creating sources from compressed formats, if the archive contains only one file, a single source will be created. If the archive contains two or more files, a composite source will be created.
