Generally any database contains two types of files: data files and log files. The data file contains the original data which is stored in the database and log files contain the log of the entries made to the database. FDB files are data files which are associated with database.
The organization of these files is similar to and SQL database. These files are created by Firebird database software. The main function of creating these files is to store the data in the form of discrete data files which allows the software to search and access the specific data easily and quickly.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .FDB file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .FDB file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .FDB file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
There may be several reasons why you cannot open the file with .FDB extension. Directly on this website you can find a solution of the most common problem with the .FDB file – that you do not have on your computer the appropriate program to open the file.
