What version? Adaptec software has been released with the Roxio name in the last few years and Easy CD 5 has had some updates. There are a number of characters not allowed in file names. Adaptec's web site used to have a Glossary that included the list of allowed characters in file names. Names should be kept fairly short. I use a mix of - or _ or Capital letters rather than spaces. "Long File Names (30 chars max.): Select this option to specify the use of long file naming for your CD. This option applies to the ISO 9660 File System only." from Easy CD 5 Help file. Early versions of Adaptec's Easy CD Creator had a problem with "too many" small files -- like a researcher might save as plain text e-mails with helpful tips at the rate of several hundred per month. About 300 mb of small files was more likely to be successful than 600 mb of small files. DVD writer software may have similar issues with "too many" files. A mix of genealogy files and pictures was okay at 4.1 GB but only tried 2.4 GB on the DVD with a lot of saved e-mails and similar notes. Elizabeth ----- Original Message ----- From: "Richard Felts" > I'm using Adaptec software to save genealogical files on CD-R's. For census images, the file names include alphanumeric characters and the dash symbol. To help locate files more easily, I use rather long file names that are very descriptive. > > Recently I filled my first CD and decided to "close" the CD. (The Adaptec software says the CD must be "closed" so it can be read on virtually any other CD reader on any computer.) During the closing process, error messages appeared saying my file names were not acceptable. There was no mention of a specific problem with the file names but the software offered alternative names that appeared to be shorter. It looks like several characters at the end of each file name were replaced with a tilde.
