It’s easy to guess that the files we download and install on your computer are exactly what they say.After all, an app with the correct name that matches a high quality icon looks legal: why Do not ?? Malware (and malware developers) thrive under these assumptions because their goal is to open these malicious programs without a doubt. Fortunately, it’s easy to find out the specific app, program, or file type on your Mac or PC. Not enabled by default.

There are settings built into both macOS and Windows that display the file extension of the file on your computer next to the name. Final Cut Pro.app is displayed instead of Final Cut Pro. Instead of EldenRing, you’ll see EldenRing.exe. It appears in all files on your computer and may not be suitable for some users. Not revealing the file type is an aesthetic choice and I understand it. It looks much better to view all the apps and files on your PC without these 3 or 4 character extensions at the end.

The important thing is not to scare every .exe you find.Rather, when the file is should not do The .exe is displayed as one. Note: If a file or app downloaded from the internet, or a message attachment looks rough, be careful and don’t open it.

This setting is also useful in other ways. Especially when it comes to compatibility, it can be important to know the specific file type you are using. For example, images come in many different file types, and knowing that you have a photo is not enough to identify what is in front of you. The image can be .jpeg, .pdf, or .heif. You will immediately know if your computer will tell you.
