Hello,

Could I can get information about sheets name in files at one folder without
open all this files.
I need list:
file1.xls sheets1
file1.xls sheets2
file1.xls sheets3
file2.xls sheets1
file2.xls sheets2
....
with open files it is no problem, but it took lot of time (about 50 files).
Could I make it faster?

Regards,
Bartosz
