| FAT Long File Names |
| =================== |
| |
| NOTE: If CONFIG_FAT_LFN is defined in your NuttX configuration file, then |
| there may be some legal, patent issues. The following was extracted from |
| the entry "File Allocation Table from Wikipedia, the free encyclopedia: |
| |
| "On December 3, 2003 Microsoft announced it would be offering licenses |
| for use of its FAT specification and 'associated intellectual property', |
| at the cost of a US$0.25 royalty per unit sold, with a $250,000 maximum |
| royalty per license agreement. |
| |
| o "U.S. Patent 5,745,902 (http://www.google.com/patents?vid=5745902) - |
| Method and system for accessing a file using file names having |
| different file name formats. ... |
| o "U.S. Patent 5,579,517 (http://www.google.com/patents?vid=5579517) - |
| Common name space for long and short filenames. ... |
| o "U.S. Patent 5,758,352 (http://www.google.com/patents?vid=5758352) - |
| Common name space for long and short filenames. ... |
| o "U.S. Patent 6,286,013 (http://www.google.com/patents?vid=6286013) - |
| Method and system for providing a common name space for long and |
| short file names in an operating system. ... |
| |
| "Many technical commentators have concluded that these patents only cover |
| FAT implementations that include support for long filenames, and that |
| removable solid state media and consumer devices only using short names |
| would be unaffected. ..." |
| |
| This Wikipedia entry has been updated with recent legal decisions in favor |
| of Microsoft. Refer to: |

| https://en.wikipedia.org/wiki/File_Allocation_Table#Patents |
| |
| So you have been forewarned: Use the long filename at your own risk! |
