- 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:
-
- http://en.wikipedia.org/wiki/File_Allocation_Table#Legal_issues
- So you have been forewarned: Use the long filename at your own risk!
