FDB file extension is used with database files native to Firebird software, a utility designed for SQL database administration on Windows, Unix, macOS (OS X) and Linux operating systems. FDB files are used for storing Firebird database files.
.ACCDB file format is used as standard file format for database files by Microsoft Access Database Management System. This file type is used by MS Access 2007 and later versions. The earlier versions used .MDB and there are a number of features added to .ACCDB over .
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the FDB file after converting to ACCDB may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from FDB to ACCDB to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting FDB to ACCDB does not meet your expectations, you can simply try to find on the Internet a different version of your file in FDB format, properly converted to a ACCDB file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file FDB the desired result was not achieved, you can try to change the format of FDB file to other than ACCDB. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your FDB file converted by someone else, and the attempt to convert it to ACCDB on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the FDB file in its original format (without conversion to ACCDB file). Such a solution will be difficult to implement, but it certainly will give the best result.
