The GRE file extension is important to know about, as it can be applied in a variety of different scenarios and using a multitude of different file formats. Whether you're a programmer, a graphic designer or a researcher, the format of your GRE file depends on the software that created it. Therefore, it's crucial to know about the different possible applications of this file type.
Graphics Rule Editor (GRE)
The GRE could denote a Graphics Rule Editor file in the field of computer programming. These files, used by pipeline tool software like StaMPS/CReSIS, store rules for processing input data. As such, these GRE files are not meant to be opened manually. However, they're encoded in simple text format, so they can be viewed and modified with a text editor like Notepad++ or Sublime Text.
Generic Routing Encapsulation (GRE)
GRE can also stand for Generic Routing Encapsulation - a network protocol used to transport packets over the internet. It doesn't exactly have a file format or file extension per se, but rather packet structure that software or hardware (like routers) need to understand. Networking software and hardware from brands like Cisco or Juniper usually support GRE.
Group records data (GRE)
In scientific research or data management, GRE can stand for group records data. Record-keeping software and data analysis applications like Esri's GIS often use this type of GRE file. To edit or even view these files, you will usually need the specific piece of software that created it.
GRE File Important Information
It's critical to quickly mention some important general information concerning GRE files. If you have a file that ends with the .gre extension but you don't know how to open it, try double-clicking it first. If it doesn�t open, or if it doesn�t work the way you expected it to, try installing the software mentioned in the previous chapters. If even then you cannot open your .gre file, it might be worth attempting to contact the provider of your software package for further assistance.
