Thanks.  This definition helps.  The file contains genomic sequence information, but I've never come across this type of file until now, and I'm not sure what tools can interpret and manipulate this type of file.

Thanks. This is helpful.  I've never seen this extension before.  What is Salmon generally usually used for in genomics?

Can you provide a little more context as to where you have seen this file and what part of bioinformatics you are working in.

You should provide more context, otherwise one can only guess what is it you are looking for! In case you are asking about Salmon's output, below is from their documentation:

Salmon’s main output is its quantification file. This file is a
  plain-text, tab-separated file with a single header line (which names
  all of the columns). This file is named quant.sf and appears at the
  top-level of Salmon’s output directory. The columns appear in the
  following order:

Name   Length   EffectiveLength   TPM   NumReads
