It works perfectly for me. I was able to open an mbox file of over 200MB. I am running windows 10 on a lenovo laptop. I use this program to open mboxes that someone gave me at archive dot org.
ripl, the problem you complained about with large .mbox files is solved! MBox Viewer is a very nice program! The author, Enea Mansutti, has updated it (January 21, 2015) to work with very large .mbox files. It now works well for me on 64-bit Windows 7 to read a 14.9 GB .mbox file containing my saved gmail archive (which I downloaded from Google Takeout). Of course, the initial load of a 14.9 GB .mbox file takes a long time, but that's unavoidable, because the .mbox file format has no index. So any program which reads it has to read the entire file, to build an in-memory index. Enea also enhanced the main display, to show "to" addresses (instead of just "from" addresses), and he added an "attachment" indicator. He also apparently incorporated some performance enhancements. He also enhanced the search function considerably. The search can now still search entire message bodies as before (i.e., search the entire .mbox file, which is slow!), but you now also have the option of searching just the message headers, which are kept in in memory, so that's fast! Also, you can constrain the search to include just a desired range of dates, which is very useful. Enea made all these improvements just because I emailed him and told him that the old version didn't work on my giant .mbox file, and asked him whether there was an updated version. What a nice guy!
