[Value] DT_PATH_ELLIPSIS [Meaning] 
For displayed text, replaces characters in the middle of the string with ellipses so that the result fits in the specified rectangle. If the string contains backslash (\) characters, DT_PATH_ELLIPSIS preserves as much as possible of the text after the last backslash. The string is not modified unless the DT_MODIFYSTRING flag is specified. Compare with DT_END_ELLIPSIS and DT_WORD_ELLIPSIS.
