My phpmyadmin is not working. How can I make it work again? I have a very large database.

I have the following files. db.opt , scraped_user.frm , scraped_user.ibd is there a way to recover my database from these files? I just want to get the table's data.

I want to reinstall my xampp but is there a way to back up my db when I can't run it? Like copying this folder 'DBNAME' with files db.opt, scraped_user.frm, scraped_user.ibd.

I tried the first option suggested by InnoDB above. Still not working. In second I cant remove the .ibd file. I don't have a backup of my table. On the third item, I don't know where it is located. Been looking for it.
I have managed to recover my data. (so happy)

After hours of reading forums and solutions I found a way to fix it. Here's what I did:


In xampp I backed up my old copy (after crash) of folder DbScrapes (dbname) from C:\xampp\mysql\data with files db.opt, scraped_user.frm, scraped_user.ibd
In C:\xampp\mysql\data I backed up an old copy (after crash) of files ib_logfile0, ib_logfile1, ibdata1.
Uninstalled my xampp
Restarted my computer to be sure ports that xampp is using will be close
Checked if there is a MySQL service in services.msc
On my computer there was a MySQL service.
I deleted it using cmd command sc delete "service_name"
Restart again to make sure everything is fresh.
Installed a new copy of xampp
Test if apache and MySQL is ok, if it's ok click stop
Copy the files that I have backed up to the location where I get them so it's C:\xampp\mysql\data
Run xampp's apache and MySQL again.


Now I'm running xampp and I have my data.

Note: Don't delete ibdata1 - it will delete all your database tables.

The crashing issue I think was a bug in xampp.
