How can I view the binary contents of a file natively in Windows 7? (Is it possible.)

If you have powershell version 5.0 or later, you can use the powershell built-in function Format-Hex

PS:21 C:\Temp >Format-Hex application.exe

            0  1  2  3  4  5  6  7  8  9  A  B  C  D  E  F

00000000   42 4D 5E 00 00 00 00 00 00 00 36 00 00 00 28 00  BM^.......6...(.

00000050   71 FF B7 59 71 FF B7 59 71 FF B7 59 71 FF        q.•Yq.•Yq.•Yq.

Built in, quick and dirty: start powershell, execute:

gc -encoding byte -TotalCount 100 "your_file_path" |% {write-host ("{0:x}" -f $_) -noNewline " "}; write-host   

TotalCount is count of bytes you want to read from file.

Google 'powershell hexdump' to get much more polished/workable versions.

If you have Windows Resource Kit Tools (not exactly built in, but close) you may also use a cmd line utility called list.exe. It's a small editor with hex mode. Designed specifically to work with big files:

List Text File Tool (List) is a command-line tool that displays and searches one or more text files. Unlike other text display tools, List does not read the whole file into memory when you open it. It allows a user to edit a text file in a hexadecimal format.

List is useful for displaying text or log files remotely, and for use on servers where administrators are concerned with degradation of system performance.

You need a "hex editor". I've used "Hex Editor Neo" for years and it's very good. It's available in free and paid versions. (And I'm sure there are other similar tools available.)
