This file extension falls into the category of GIS files. The .JGW extension stands for JPEG World File and was developed by the developer ESRI. This is a file type which contains geo-referencing information for raster maps. It is required that the .JPW file has the same name as the matching map saved in the same directory. This offers the actual world coordinate details that makes it possible for the corresponding .jpg to be positioned on the map or mapping system accurately. These .JGW files are mainly used by GIS products like ESRI ArcGIS Desktop. The format of this file type is known to be identical to a .tfw file.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .JGW file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .JGW file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .JGW file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
There may be several reasons why you cannot open the file with .JGW extension. Directly on this website you can find a solution of the most common problem with the .JGW file – that you do not have on your computer the appropriate program to open the file.
