How do I decompress .bgz files?

Question

Is there any software that will decompress a file named nnnnn.tsv.bgz on a PC running Windows 10? The usual R commands will not do it.

Answer 1

It looks like it's a "block gzipped" file and should be viewable with anything that knows gzip files (tar, gzip, etc). Winzip/7zip might just need it's extension changed to .gz (windows is funny that way).

Or Install the Windows Subsystem for Linux and use linux tools, like tar, gzip, file, bgzip (provided in the tabix package in Debian & probably others)...

Or it could be a Blood Frontier game Map File, so use the game.

Answer 2

That file extension sounds suspicious. What i would do is check the first hex values of the file in a hex viewer to see really what kind of file it was. How is it encoded or is it an archive, who knows. But, the first hex values in a file will usually not lie and say what they are--these are the "magic bytes"

First is a well-used resource showing common file types and their hex values.

Lastly is an easy place to just upload it and have it checked

Answer 3

Try the freeware 7-zip: https://www.7-zip.org/

It can decompress archive of many known file types.

Answer 4

I suggest using WSL (Windows Subsystem for Linux) with command below to unzip:

gunzip -c nnnnn.tsv.bgz > nnnnn.tsv

Or:

gzcat nnnnn.tsv.bgz > nnnnn.tsv
