YahArch is an archive viewer for Yahoo Messenger. It allows you to quickly and efficiently views all archives in your Yahoo Messenger folders and also has support for opening archives that are saved in other locations. You do not need to be logged into Yahoo Messenger to view these archives.
YahArch supports almost complete visual formatting: timestamps, fonts, colors, color effects (alternating and fading), smileys and hyperlinks. Most of these can be toggled on/off in case a user prefers some over the others. With all of these formatting capabilities, YahArch remains approximately 10-20x faster than the native viewer. Additional features include Saving (HTML or text), printing, find/find next and an advanced search, which allows you to quickly search through all of the local archives for specific phrases.
