Opening an unfamiliar file can call for a viewer that handles its format without requiring the software that created it. Compared on archive, code and office file previews, these options also show listed formats, maximum file size, in-file search and primary access. Free-plan availability and paid-from pricing help you weigh cost alongside those capabilities. ViewAnyFile.app, Okular and Universal File Opener are among the entries to consider. Check the formats and file sizes you need to inspect, then compare whether archive or code previews and in-file search suit the files you work with.
