I suppose that your file is much larger than its content and that you have innodb_file_per_table turned off. This was the default setting for mysql server, but with the last version, the default value is on.

The Innodb files grow on need, but do not shrink. In fact, it is not even possible to shrink them.

I had a similar situation some time ago. The solution was to turn on innodb_file_per_table (add 'innodb_file_per_table=1' in my.ini file). Then I exported the whole database in a text file and deleted the Innodb .idb file.
It is not sufficient to delete the database, you also need to delete the file.

When you import the data from the text file, there will be a file per table. With this configuration it will be easier to manage the disk space used.
