VBA to search multiple values and multiple workbooks and return filename where found

[AggyRJ]

I am attempting to create a tool where I input a list of values (20-25 as I don't want the code to take forever) and then Excel does a search across multiple workbooks and for each value in the list and returns what workbook it is located in and where it is within that workbook.

On another page I found a code that mostly does this, however it has a few limitations. I will post it below but this is what it does:
1. Defines the path that contains all of the workbooks to be searched
2. Defines what I am searching for
3. Creates a new worksheet with all of the search results which tells me the name of the workbook, the worksheet where it is found, and which cell it is in.

I need to add a few key abilities to this:
1. Have the path change to sort through multiple folder directories (I was thinking of typing out a list of all possible directories and having it loop through each one)
2. Search for more than one value (again I was thinking of limiting it to a list of maybe 20-25 values)
3. Add the folder directory (this is crucial as the file names themselves are all the same, they are just located in a different folder).

So. to summarize:
1. I am trying to search multiple values one at a time (from a list I will type in each time so the entire list will change each time I perform the search);
2. Through multiple folders (from a list that I type in that will not change);
3. Have a list returned of the folder where the workbook is located, the workbook name, the sheet name, and where the cell it is located at.

One last thing - I am not married to this code so if someone has something better then by all means please tell me. I am pasting what I found below.
