Holy cow, Bill. I have not used DOS in 20+ years. Thankfully the commands are relatively basic and simple.
To change to another drive and then to another directory is easy.
***Leave out the quotation marks in my examples.***
1. In the command prompt, simply type and enter "G:"
2. Once in G:, change to the sub-directory by typing and entering "CD\USB3 Fix" (Note the back slash, not front slash)
3. When in a command prompt, you can review the directory files by typing and entering "DIR"
4. To get back to C:, simply type and enter "C:"
5. Entering "CD.." takes you back one sub-directory at a time until you hit the root directory
6. Entering "CD\" immediately takes you to the root directory of whatever drive you're in
7. Entering "Exit" closes the command prompt
You can go straight to a deep sub-directory by entering "CD\FirstDirectory\Second\Third\Fourth\AndSoOn"
BTW: The commands are not case sensitive. Also, in DOS a "folder" is called a "directory". Thus the command CD means Change Directory.
DOS is unforgiving to any typos or misspellings. If a command does not work, double check the characters, spaces (if any), etc.
Scuzzy; thanks for the walk down memory lane.
