It should tell you when you attempt to burn it.
The ISO 9660 format is the original standard file system for CD data discs. The format is recognized on several operating systems, including MSDOS, the Mac OS, UNIX, and the Windows operating system. The ISO 9660 format is published by the International Organization for Standardization (ISO).
The format begins at sector 16 with the volume header, CD0001; the remainder of the header follows. Other derived formats also begin at sector 16, but use another string for the volume header. For example, High Sierra discs use the string CD-ROM0001 and Compact Disc Interactive format uses CD-I0001.
The header points to areas of the disc that store the file names in ISO 9660 format. The file and directory naming convention consists of 8 characters, a period, and 3 more characters. This is the same naming convention used by the MSDOS operating system.
Additional file system headers, for formats such as Joliet and UDF, can co-exist on a disc without affecting the readability of the ISO 9660 format. After the indexes, a set of data files occupy the disc. The indexes for each file system independently reference data files on the disc.
The ISO 9660 specification defines three levels of the format:
The Joliet format is a derivative of ISO 9660. This format writes the Joliet file system index to the disc image in addition to the ISO 9660 file system index.
The Joliet index provides the following improvements to the file system index:
Because the Joliet format preserves the ISO 9660 file system on a disc, compatibility with ISO 9660-compliant devices is retained.
Universal Disk Format (UDF)
The Universal Disk Format (UDF) is a newer file system developed for optical media by the Optical Storage Technology Association (OSTA). UDF is a portable format that is recognized by several operating systems. UDF is replacing ISO 9660 as the new standard, especially with read/write media.
Features of UDF include the following:

It does not tell me when I burn a disc. Windows explains when you should use either the Live or the Mastered format but that's it.
I've read all the other info about ISO 9660, Joliet, & UDF. I burned a DVD data disc which had jpg photos on it. It is a data disc, but I want to view the images using a DVD player. It does work so there is no problem. But I was wondering if Joliet was used and if ISO 9660 level 1 or 2 was used.
I noticed Windows 7 does not finalize the disc but just closes the session, which means you can add to it. And there appears no way to select which one you want to do.
I was just curious what Windows7 is really doing.
