Please Help!!

I have a master file called "All Reports.xls" that opens up various Reports
files(Ex: ABC_G016_GPUS.xls, BCD_G027_GPUS.xls, JKL_G034_GPUS.xls). The
Report files are in the same network folder as the master file and are
updated frequently. The Report files also have names that constantly change
when they are updated. The only part of the filename that does not change
begins with "G" followed by 3 numbers. By reading previous posts, I was able
to figure out how to open the "G016" Report file with the code below.

Workbooks.Open ActiveWorkbook.Path & "ABC_G016_GPUS.xls"

How do I open the file by only the "G016" part of the filename? I tried the
code below, but it did not work:

Workbooks.Open ActiveWorkbook.Path & "*" & G016 & "*.xls"

I appreciate your help!!
