Back in the day, when I was cutting my computing teeth on classic Mac OS I used a tool called ResEdit to create and edit resources within a Mac file.
The app was simple enough to use, had a typical Mac GUI, and it was useful to edit and customize menus and other elements in an app. Those days are gone, but I still get curious about what makes up a Mac file. One of the newer tools to dig into files is Smart File Examiner Pro.
3 Elements, Incomplete
A Mac app like ResEdit might be useful for non-programmers these days, but Smart File Examiner Pro is easier to use, though limited to three basic file components.
SFEP, for short, opens files in advanced hex mode and display information not easily determined by Get Info.
First, it displays basic file information, including name, permissions, type, owner, group, creation date, modification date, file size, and the last accessed date for the file.
Second, you’ll also get a look at the hex file header. Is that important? Only if you know what it means. Any good hex editor will do the same thing, but SFEP gives you a quick look at what’s inside.
Finally, SFEP also displays various hash types from the file. These include SHA, MD4, MD5, SHA1, SHA224, SHA256, SHA384, SHA512, and RPEMD160.
The interface couldn’t be much simpler. You get six choices. Exit. Select File. Help. Basic Information. Advanced Information. Hex Header.
Click to open a file.
Click to view Basic Information from the file, Advanced information, or Hex Header. That’s it.
All the information you want from your selection is available with a click, and displayed in the drop down box below each menu selection.
Smart File Examiner Pro helps to satisfy your curiosity about files, but can be useful when downloading files from the internet that need an extra layer of examination for file validity.
