FILE_CASE

This configuration variable allows you to adjust the case of data file names. Possible values are:

0
(default) No translation of the name is done.
1
Data file names are translated to lower case.
2
Data file names are translated to upper case.

Translation occurs before the FILE_SUFFIX and FILE_PREFIX configuration variables are applied. Be sure that these variables specify the correct case.

File name translation does not occur if the file name starts with -F, -D, or -P. (See the User's Guide, section 2.8, "File Name Interpretation.")
