I think your search for a "standard" naming convention will be in vain. Here are my proposals, based on existing, well-known programs:
A) C:\users\OddThinking\Documents\My Source\Widget\foo.src
Vim calls it file root (:help filename-modifiers)
B) C:\users\OddThinking\Documents\My Source\Widget\foo.src
file name or base name
C) C:\users\OddThinking\Documents\My Source\Widget\foo.src (without dot)
file/name extension
D) C:\users\OddThinking\Documents\My Source\Widget\foo.src (with dot)
also file extension. Simply store without the dot, if there is no dot on a file, it has no extension
E) C:\users\OddThinking\Documents\My Source\Widget\foo.src
top of the tree
No convention, git calls it base directory
F) C:\users\OddThinking\Documents\My Source\Widget\foo.src
path from top of the tree to the leaf
relative path
G) C:\users\OddThinking\Documents\My Source\Widget\foo.src
one node of the tree
no convention, maybe a simple directory
H) C:\users\OddThinking\Documents\My Source\Widget\foo.src
dir name
I) C:\users\OddThinking\Documents\My Source\Widget\foo.src
full/absolute path
I found this larger function in the Chyrp code:
/**
* Function: sanitize
* Returns a sanitized string, typically for URLs.
*
* Parameters:
* $string - The string to sanitize.
* $force_lowercase - Force the string to lowercase?
* $anal - If set to *true*, will remove all non-alphanumeric characters.
*/
function sanitize($string, $force_lowercase = true, $anal = false) {
$strip = array("~", "`", "!", "@", "#", "$", "%", "^", "&", "*", "(", ")", "_", "=", "+", "[", "{", "]",
"}", "\\", "|", ";", ":", "\"", "'", "‘", "’", "“", "”", "–", "—",
"—", "–", ",", "<", ".", ">", "/", "?");
$clean = trim(str_replace($strip, "", strip_tags($string)));
$clean = preg_replace('/\s+/', "-", $clean);
$clean = ($anal) ? preg_replace("/[^a-zA-Z0-9]/", "", $clean) : $clean ;
return ($force_lowercase) ?
(function_exists('mb_strtolower')) ?
mb_strtolower($clean, 'UTF-8') :
strtolower($clean) :
$clean;
}
and this one in the wordpress code
/**
* Sanitizes a filename replacing whitespace with dashes
*
* Removes special characters that are illegal in filenames on certain
* operating systems and special characters requiring special escaping
* to manipulate at the command line. Replaces spaces and consecutive
* dashes with a single dash. Trim period, dash and underscore from beginning
* and end of filename.
*
* @since 2.1.0
*
* @param string $filename The filename to be sanitized
* @return string The sanitized filename
*/
function sanitize_file_name( $filename ) {
$filename_raw = $filename;
$special_chars = array("?", "[", "]", "/", "\\", "=", "<", ">", ":", ";", ",", "'", "\"", "&", "$", "#", "*", "(", ")", "|", "~", "`", "!", "{", "}");
$special_chars = apply_filters('sanitize_file_name_chars', $special_chars, $filename_raw);
$filename = str_replace($special_chars, '', $filename);
$filename = preg_replace('/[\s-]+/', '-', $filename);
$filename = trim($filename, '.-_');
return apply_filters('sanitize_file_name', $filename, $filename_raw);
}
Update Sept 2012
Alix Axel has done some incredible work in this area. His phunction framework includes several great text filters and transformations.

Yes, they are named LONGFI~1.DLL and LONGFI~2.DLL (all letters capitalized in 8.3 file format). Which is which is determined by the order they are created.
In a cmd window you can type dir /x to view the short file names as well.
