[beyondzhu]

for e.g.
D:\abc\
there are 3 sub-folder in abc folder, named level1sub1 ,level1sub2,level1sub3,and every level1sub-folder have level2sub-folders and files
and also there are 5 files in abc folder,named file1,file2,file3,file4,file5

I want to search the files only in abc folder, not in other sub folders.

so how to do this .

advance: How to search files limited in level3sub folder,not search the level4sub folder or level5sub.......
