open multiple files with simular file names

Question

I want to open multiple file with the same file names but have extra characters. Here is an example of the file names. 12-1234-13 sht1 12-1234-13 sht2 12-1234-13 The extra characters will not be in all of the file names. I will not know which file will have them and which files will not. I was able to write a program to open the file with the 10 characters but I could not get it to open the other files with the exta characters. I don't know how to approch this. Any help will do. Thanks for all the help. sdig
