What is a JGW file?
JGW file format is used by various versions of GIS products, such as ArcGIS or MapInfo. This type of file contains georeference data saved as raster image. Spatial coordinates are stored in JGW file as raster JPG image.
JGW file specifies image scaling and information regarding the coordinates of the top-left corner pixel. JGW files can be used for generating aerial maps of actual geographic area.

How to open JGW files
If you cannot open the JGW file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports JGW among those that are installed on your device.
A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the JGW file can be found in the table. Now just download and install the appropriate application.
Possible problems with the JGW format files
The inability to open and operate the JGW file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the JPEG World Format file. Below is a list of possible problems.
- Corruption of a JGW file which is being opened
- Incorrect links to the JGW file in registry entries.
- Accidental deletion of the description of the JGW from the Windows registry
- Incomplete installation of an application that supports the JGW format
- The JGW file which is being opened is infected with an undesirable malware.
- The computer does not have enough hardware resources to cope with the opening of the JGW file.
- Drivers of equipment used by the computer to open a JGW file are out of date.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the JGW file should operate with your programs without any problem. If the problem with the JGW file has not been solved, it may be due to the fact that in this case there is also another rare problem with the JGW file. In this case, the only you can do is to ask for assistance of a professional staff.
How to associate the file with an installed software?
If you want to associate a file with a new program (e.g. my-file.JGW) you have two ways to do it. The first and the easiest one is to right-click on the selected JGW file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the JGW file extension to the corresponding software in the Windows Registry.
Is there one way to open unknown files?
Many files contain only simple text data. It is possible that while opening unknown files (e.g. JGW) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
