Easily combine text or csv files

I am totally nerding out. I admit it. I had a folder full of text files, and I wanted to dump them all into a single Excel worksheet. It turns out there is a super-easy way to do this, provided you're willing to open up a command line and type in a few DOS commands!!

Here's where I found the instructions:  https://www.rondebruin.nl/win/s3/win021.htm

In my case...

1. I put the .log files (which are all really text files with a fancy extension) in a folder named "logs" on my desktop
2. I clicked on the Windows Start button and typed cmd to open a command prompt
3. My path showed that I was already in my user account. 
4. I typed cd desktop/logs to navigate to the "logs" folder on my desktop
5. I typed copy *.log all.txt  to copy ALL the .log files into a single text file titled "all.txt"
   
6. Then I opened Excel, chose File->Open and navigated to the all.txt file

I am ridiculously excited about this trick!
