Thanks for all of the helpful responses to my question about permissible file names on CD's. Here's a brief summary of what I've learned. You must use the Joliet format, not the ISO 9660 format, if you want to use long file names on a CD. The maximum length of a file name is 64 characters. Based on some experiments I did this morning, the 64-character file name is in addition to any path designation (folders and subfolders). In other words, if you save a file in a folder called "Images" you do not need to reduce the length of the file name by 6 characters to stay under the 64-character limit. However, it appears that the file extension DOES count in the 64-character limit but the period between file name and extension does NOT count. So you can have a 61-character file name followed by a period and a 3-character extension. By the way, I'm using Adaptec Easy CD Creator 4. I know there are certain characters that are not permissible in file names but I didn't explore that question because I use only letters, numbers, spaces and dashes. Hope this helps put the matter to rest.

(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. > > I've scoured Adaptec information for any guidance about file names but haven't found a thing.
