That is not a problem of UltraEdit, it is a windows problem. If you don't believe me, try dir *.sas at a command prompt. The reason is the 8.3 short file name format for compatibility issues.
A file like test.sas7bdat has in 8.3 format the name test~1.sas. So the windows kernel functions FindOpen, FindFirst and FindNext always also returns *.sas7bdat files to the calling procedure, because the short file name extension for such files is *.sas.
