Opening RSRC files

Did your computer fail to open a RSRC file? We explain what RSRC files are and recommend software that we know can open or convert your RSRC files.

What is a RSRC file?

Files that contain the .rsrc file extension are most commonly associated with Macintosh resource files. The file format was initially created in 1978 for use with the pre-Macintosh Apple Lisa computers.

An RSRC file contains a library of information that is used by the Macintosh OS operating system. This file format made it possible for the Mac OS to separate graphics and text in a file through the use of data and resource forks.

RSRC files are also used in the Apple Xcode environment to develop programs for Mac OS versions 9 and earlier. RSRC files may also contain system themes for the Mac OS X interface.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
