OSRM Toolchain Files

There's a Toolchain-file-overview wiki to introduce OSRM generated files. This doc will deep dive into these files to understand more.

Files Format

As described in Toolchain-file-overview wiki, all the files generated by OSRM are standard tar format, so it's possible to extermine/extract the contents of the files using tar tvf <filename>.osrm.* or tar xvf <filename>.osrm.*.
E.g.

tar -tvf nevada-latest.osrm.nbg_nodes 
-rw-rw-r--  0 0      0           8 Jan  1  1970 osrm_fingerprint.meta
-rw-rw-r--  0 0      0           8 Jan  1  1970 /common/nbn_data/coordinates.meta
-rw-rw-r--  0 0      0     9137888 Jan  1  1970 /common/nbn_data/coordinates
