All content (pages, posts), settings (navs, headings, etc.) are stored in and retrieved from the database; there are no files to look for for these items. The only files that the user adds to a WP site, generally, are in the wp-content folder and in the enclosed themes, plugins and uploads (only if you have uploaded anything) sub folders. Any media (images, videos, etc.) are stored in the wp-content/uploads folder (and any resulting sub folders, depending upon how you set it up).
If you were now able to get a version of WP running, did you create and use a new database? Sounds as though you did as there is no "previous" content.
To sum up, generally, each WP install will have the following files and folders:
- wp-config-sample and/or wp-config (depending upon how you set it up)
Now you can see why it is a good idea to have each site, even if it's only one, in a separate folder in htdocs :-)
For example, my htdocs folder in MAMP has only these items (folders only):
- joomla302 ...oops! ...how did that get in there :-)
The default databases that are in the latest MAMP 3.0.5 are the following system databases; do NOT edit or otherwise mess with these :)
Generally, you create a new, empty database for every WP site in your MAMP installation.
How many others do you have now other than the above-mentioned three?
