Corel WordPerfect is a word-processing application developed by Corel Corporation. It is also distributed as part of the Corel WordPerfect Office suite for Microsoft Windows.
IRS files contain resources for Corel WordPerfect. They support the application as settings or other program resources rather than storing the contents of a WordPerfect document.
The format is tied to the Windows versions of WordPerfect and is intended to remain with the software installation. It is not a general-purpose document interchange format.
Open an IRS file with Corel WordPerfect on Microsoft Windows, if the installation requires the file. In normal use, WordPerfect reads this type of resource file automatically rather than opening it as a document.
Do not edit or rename the file unless instructed by WordPerfect documentation or technical support, because changing a program resource can affect the application's operation.
IRS files are program resource files, so they do not have a meaningful document conversion or export workflow. Corel WordPerfect does not normally convert them into another user-facing file format.
If the goal is to convert document content, open the relevant WordPerfect document in WordPerfect and use its Save As or export options; that process does not convert the IRS file itself.
