What is a RWT file?
A .RWT file is an educational project file created by ReadWriteThink interactive tools. These files save student work so users can resume projects later. The format is heavily associated with the ReadWriteThink Timeline and the ReadWriteThink Printing Press Draft tools. These educational resources are supported by the International Reading Association. Depending on the exact tool used, a .RWT file might store data using XML, JSON, or zlib compression.
How to open RWT files?
The primary method to open a .RWT file is to upload it back into the corresponding ReadWriteThink web application. For instance, a timeline file must be loaded directly into the Timeline Creator tool.
If you do not know which tool created the project or the site is unavailable, viewer.online/rwt analyzes .RWT files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
Because the .RWT extension has multiple possible meanings and internal structures, we recommend using viewer.online/rwt to identify the actual format of your file. If your file is stored in plain XML or JSON, you can rename the extension to .txt and open it with a source code editor like Notepad++ to read the raw text. If the file contains zlib compressed data, you must use decompression tools before you can read the internal text.
Summary
Because .RWT files use the known XML format, viewer.online/rwt can safely open and display them online, eliminating compatibility problems.
