Find and replace in batch for Excel files in a selected directory add-in button written in VSTO C#

*** Disclaimer: Although this add-in has been tested and proven to be working, all risks and responsabilities go to the user of the add-in.

Functionalities:

1. The "Find and Replace" button works for xlsx, xls, xlsm, xltx, xltm, xlt files, and "Find and Replace XLT" works for xlt files only. You have to select the folder where you would like to make the replacement, and all the Excel files will be overwritten with the new changes.
2. The replacement will be made for part of a string as well, for example "firstaaaa" will be replaced into "secondaaaa".
3. If the file doesn't contain the targeted string, it will not be modified
4. It does not replace the files in a subfolder in the selected folder
5. The program will stop if one of the Excel files is protected
6. The program will stop if one of the Excel files is "read-only"
