PowerArchiver has a Internal Viewer that supports TXT, RTF, BMP, JPG, TIFF, GIF, PSD, PSP, PNG, JPG, FAX, BW, RGB, SGI, TGA, PCX, PCD, PPM, CUT, RLA, RPF, ICO, WMF and EMF files. It comes in handy when you want to quickly view files, but it is not meant to replace full-fledged viewer applications.
If you select several files in PowerArchiver to be viewed, you will be able to go through them by using the „Next“ and „Previous“ buttons.
