opening pe4 files

[KayGee]

i was looking for wallpapers recently and downloaded a file which had the extension pe4. i looked it up on google and found that it was a photo archive which could be opened by ulead photoimpact v.4.0 or ulead photo explorer. i downloaded trial versions of photoimpact (v.10) and explorer (v.8.5), but both programs were unable to open these files. anyone have any suggestions? thanks.
