Unfortunately I uninstalled Xampp in my windows machine, there are about 50 databases in /xamp/mysql/data folder. I have not taken backup script, but I have a copy of Xamp/mysql/data folder.How can I restore MySQL Databases using that Data Directory.
Thanks in Advance

I was find out solution
- Install new xampp
- Copy your old database folder from
xampp\mysql\data\databasefolder to Paste in your running xampp folder
C:\xampp\mysql\data - After that stop mysql and apache service then backup your running xampp files ib_logfile0,ib_logfile1 and ibdata1 and store in safe place
- Then Copy same file (ib_logfile0,ib_logfile1 and ibdata1) from old xampp\mysql\data\ and paste in your running xampp server C:\xampp\mysql\data\
- Start mysql and apache service Open CMD Fire command C:\xampp\mysql\bin>mysqldump -u dbusername -p dbpassword dbname>D:\exportdb.sql
- stop mysql and apache service and restore your main ib_logfile0,ib_logfile1 and ibdata1 file (check Step 3)
- after than again start service and open http://localhost/phpmyadmin/ and import database backup from D:\exportdb.sql Now your backup is working :)

I experienced with my Mac, before selling to a friend simply copy the XAMPP folder only to my hard drive. (NOT SUCCESS) Unfortunately, it was bringing trouble to me, because I tried the following steps: - I install fresh XAMPP and copy the whole \httdocs and var\mysql to my new Mac, those db only with .frm and .ibd, NOT WORKING, I can't still access the tables inside PHPMyAdmin ... - I tried to install the same xampp version and repeat the above steps, still NOT WORKING. - Decided to go to bed.
(SUCCESS) - This morning, I brought my backup disk and try with Windows 7. - Install fresh latest XAMPP for Windows, c:\xampp - I have one of website (folder) from my backup \httdocs and correspond database folder inside \var\mysql are READY in my windows 7, I just want to try with one website then try the rest because I have many projects inside httdocs\ and \var\mysql - I copy the mention httdocs\ folder to windows c:\xampp\httdocs and copy the \var\mysql to c:\xampp\mysql\data
NOT LAST YET I copy the ib_logfile0, ib_logfile1, ibdata1 from my backup file to windows xampp c:\xampp\mysql\data
I refresh the http://localhost/mywebsite
WOW WOW DONE ... it's working...
