In the biggest single sweep of its kind, German investigators charged 3,500 people with illegal music sharing, the International Federation of the Phonographic Industry (IFPI) said Tuesday.The file sharers face criminal and civil prosecution and may be asked to pay damage claims of several thousand euros each. On average, file sharers are being charged 2,500 euros\u00a0(US$3,193), said the IFPI.German authorities helped identify the file sharers, who were using the eDonkey network to share thousands of music files. EDonkey software allows users to find and share files with other eDonkey users. German police searched 130 premises for evidence in the investigations. The IFPI blames file sharers for a drop in music sales. In Germany, sales of music CDs fell by a third over the past five years, the IFPI said. However, recent research revealed that legal sales of digital music worldwide tripled in 2005. The German lawsuits follow the IFPI\u2019s announcement last month that within about five months it had sued 2,000 illegal file sharers, mainly in Europe. In addition to music associations like the IFPI, movie organizations are also stepping up their campaigns against illegal file sharing. In February, Belgian authorities arrested the operator of a server hosting and sharing millions of files, including movies, software and music. Despite the increase in suits against illegal file sharers, the bulk of Internet use continues to be by peer-to-peer file-sharing platforms. Late last year, CacheLogic said that such platforms account for 60 percent of all Internet traffic and that eDonkey is the most popular\u00a0peer-to-peer file-sharing software.-Nancy Gohring, IDG News ServiceCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
