Cannot
open file – Now it can be opened 
The error cannot open file
comes up while working on MySQL which is known as Relational
Database Management System in short RDBMS. It is program
which could be accessed by multiple users in order to
maintain the database. It consists of two storage engines
called MyISAM and InnoDB. There are .myd, .myi and .frm
files which store the data from MyISAM. If any of these
files get corrupted than it could lead to severe data
loss. We would get cannot open file
error if MySQL database will stop functioning.
Usually, we encounter cannot open file
error if the data in MySQL is corrupted. It means the
table which was used has completely damaged. However,
file system issues, program malfunctioning, hardware
issues, improper system shutdown or virus attack could
be enough to begin cannot open file
errors. In this situation any access to the particular
file would be prohibited by the system itself. It is
suggested not to fidget with the corrupted file.
However, we may try to extract the file from MySQL database
with the help of proper programs. We may try to retrieve
the data from previous back-ups as well. Then allocating
additional space with the help of hard drive could be
a good option for avoiding cannot open file
errors. We can also try to rename the repair table.
Otherwise we need to take the assistance of third party
softwares. Like Repair MySQL could be a great help in
order to repair database. It is a user-friendly interface
which makes the recovery simple. Another option could
be MySQL Database Repair which recovers from both MyISAM
and InnoDB. Moreover, it is compatible with MySQL 5.x
and 4.x. But if we don’t want to see cannot
open file error ever than the best way is to
create more back-ups for database.
