It's a generous offer and an impressive milestone -- there aren't many standalone PC software companies that have lasted 25 years, and even fewer that are still posting 30 percent to 40 percent annual growth.

Laplink started in 1983 as "Traveling Software" and pioneered the market for products to transfer files from one PC to another. It remains privately held, with only one outside investor -- Microsoft.

Along with the free download -- and giveaways such as a free laptop -- Chief Executive Thomas Koll posted a thank you message to customers on Laplink's site. An excerpt:

Laplink was here before PCs were a mainstay for businesses or consumers. We were here before the Internet boom -- and we were here throughout the dotcom boom and bust. We saw broadband connectivity become a reality and remote access become a necessity.

Today, we're still here and we're still helping businesses and consumers save time and stay connected.

Here's a link to the free software.
