[Gretl-devel] database file size

Hi, I was wondering why the file size of a gretl database is so big compared to the other storage formats. For example, I have a relatively large dataset which fills up 1.4MB when exported to csv. (Of course, gretls native and zipped file is much smaller, about 170KB.) When I save this data to gretl binary database format I get a 2MB file. And I thought that text files like csv cannot be beaten in terms of explicitness and bloat... I'm asking because I'm playing around with many such files, so while one file with 2MB is no problem, having many files with a total size in the gigabyte range isn't really feasible. thanks, sven
