The JPW file is supported on 2 operating systems. Depending on your operating system, you may need different software to handle the JPW files. Below is a summary of the number of programs that support and open the JPW file on each system platform.
What is JPW file?
The file in the JPW format belongs to the GIS Files category. It was designed by ESRI. Additionally, the GIS Files category contains 255 of other files. World Format For JPEG appears on 2 operating systems as a functional file. The file will work on Linux, Windows systems, unfortunately not on others. The ArcReader application is recommended to open the file. It was released by Esri. This file type can also be opened by 2 other programs. You can use ArcGIS Desktop in case ArcReader cannot be used.
How to open JPW file?
An often recurring problem with World Format For JPEG is that JPW is not associated with the correct program file. This is manifested by the fact that JPW files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the JPW file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install ArcReader
In this case, you should first verify that the ArcReader application is installed on the computer. To do this, enter the name ArcReader into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file JPW with ArcReader. Below is a list of programs that support the file JPW.
Programs to open JPW file
Remember to download programs supporting JPW files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of ArcReader with JPW files
If the application is or has been freshly installed, but the JPW file still does not use the ArcReader program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the JPW file with the ArcReader program.
Step 3. Update ArcReader to the latest version
If, despite the association of the ArcReader program with the World Format For JPEG file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Esri page and install.
Step 4. Check for the following problems with the JPW file
Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:
The affected file may be 0 KB or smaller than expected. This suggests truncating the JPW file contents when downloading or copying. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the JPW file that we want to open. Sometimes virus-infected JPW files cannot be recovered, so make a backup in advance.
Older version of JPW file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair JPW file corruption. The easiest way to restore the file is from a backup or by contacting ESRI, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted file JPW except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. If possible, you can try to move the JPW file to another location.
This problem only occurs with more complex files. In this case, the JPW file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the JPW file again. Some anti-virus or backup software may occupy the JPW file for a certain period of time. If nothing helps, please reset the device.
