What is a .QLGENERATOR file?
A .QLGENERATOR file is a special kind of file used on Mac computers. It works with a feature called Quick Look, which is part of the macOS system. Quick Look lets you take a peek at the contents of a file without having to open it in its usual program. For example, you can quickly view a photo, a document, or listen to a song just by selecting the file and pressing a button on your keyboard.
The .QLGENERATOR file is actually a plug-in, which is a small piece of software that adds new abilities to Quick Look. With these plug-ins, Quick Look can show you more types of files in a quick view. Some examples of these plug-ins include ones for playing audio, showing fonts, previewing documents from iWork and Microsoft Office, viewing emails, watching movies, and opening PDFs.
To make these plug-ins work, they need to be placed in a specific folder on your Mac. This folder is located at /System/Library/Frameworks/QuickLook.framework. Once a plug-in is in the right place, Quick Look can use it to show you previews of files directly in the Finder, which is the part of macOS that lets you manage your files.
The main way to use Quick Look is very simple. When you find a file you want to preview, you just select it and press the spacebar on your keyboard. This action tells Quick Look to show you a preview of the file, using any necessary plug-ins like the .QLGENERATOR files to display the file correctly.
In summary, .QLGENERATOR files help your Mac show you previews of different types of files quickly and easily, without needing to open the full application that the file is associated with. This makes it faster to check what's inside your files, helping you to work more efficiently.
