What type of file is this and how do I view or edit it under Linux?

Simply double-clicking on a file will often open it in the correct program.

If your file does not have an extension, or seems to have the wrong extension, use the file command to let the system take a guess at what type of file it is. Syntax is file filename

If unsure how to use any of the programs in this table, use the man command e.g. man bunzip2
