Opening files with only part of the name

Greetings,
I am new to VBA and trying to write a program that will open a group of files whose name is in the format S1T1C1.vfc where the S1T1 part of the name will remain constant (S refers to subject number and T refers to trial number) but the "C1" (condition) will be different every time since we randomize our trials. I have a working loop that will open all the trials for a particular subject but only if I remove the last two letters of the file name in the folder.

Is there a way to only look at the first part of the file name (which will be unique) and ignore the last two characters?

Thanks for any help you can provide,
Marcus

Are these Excel files or what other application?

A loop using Dir() as Ger posted would be the route to do it. The opening depends on the answer above.

Thanks for the help that did it. These are not excel files but I just recorded a macro with the steps to bring them in to excel.
cheers,
