Integration Services :: Open Excel File In Bad Format And Resave To New Sheet

I have a foreach loop that is processing all .xls files then moving them to a processed directory.Problem is that when I try to open the original file which is in .xls 97-2003 format, it's giving me a file error that SSIS could not read.  Found out the problem was called Extension Hardening.  I fixed it in the registry according to a website I found and I thought about writing a Batch file or Script to handle it, however SSIS still can't read unless I open and "save-as" to another format.  It even works if I still save it in 97-2003 format just has to be a different file.How can I open and resave the files (all excel files in directory through a loop) and rename them the same?

For example:
Original file named "ABCDEFG_08_15_2015.xls"

Can I loop through all files in the directory and name each one differently say "REVISED_ABCDEFG_08_15_2015.xls" so I can read them through SSIS?I think I need a @filename variable or something for that..
