RWD Compressed Game Archive | NRG Systems | Data Files |
The NRG file type is used for NRG Raw Wind Data files, which are saved in a special format used for meteorological data. This type of file is mostly associated with WindNinja, an open-source software developed by the National Renewable Energy Laboratory(NREL). It is used for generating localized winds used by energy professionals. NRG files contain multiple columns of information which represent weather variables such as air temperature, wind direction and pressure. The format can be parsed and read by many applications that are used for weather prediction and analysis.
Data Compression
The NRG file extension contains data in a RAW format which is uncompressed. In order to save disk space and to reduce file sizes, users may opt to compress the NRG data using standard archive formats such as ZIP or RAR. Once compressed, an NRG file can be identified by it's associated ".zip" or "rar" file extension.
Similar File Formats
Other types of meteorological files include .DAT, .WND, and .MPH. These types of file formats are all in some way related to the NRG format, but generally store different information in a variety of formats.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .RWD) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .RWD extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .RWD file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .RWD extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .RWD extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .RWD file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .RWD file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .RWD file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .RWD file) will be extended to the maximum.
It is also good to check
- if the .RWD file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
