Our Trekker application has been reviewed by FreewareFiles.com . They tried it out on a 250 page pdf manual and found it to open pages "in what seemed like a flash" while the pdf viewer they normally used "stalled a bit before finally opening up". While Trekker has not primarily been designed for speed, it is designed to be light on system resources, and to also allow you to split and join pdf files.
The FreewareFiles.com review gives Trekker a four out of five star rating, as well as having tested Trekker "using leading antivirus scanners and found it 100% Clean". Please visit FreewareFiles.com to read the full Trekker review.
