In the upcoming sections of this article, we will delve into the reasons behind this "Unrecognized Database Format" error. Following that, we will explore straightforward steps to resolve the issue. Keep reading to learn more.

What Causes "Unrecognized Database Format"?

This error might occur if the database file is too large, potentially due to insufficient space on the hard disk. The following are the reasons that could cause this error:

• The latest version of the file opened in an older version of the database: When attempting to open a file created in MS Access 2019/2016/2013 in an older version of Access, such as 2007/2010, the operation fails.
• File located on a bad sector: If your files are stored on a hard drive with a bad sector, the database may become inaccessible. You should check for disk errors.
• Corrupt Access database text: Various factors can damage the file, including sudden system shutdowns, corrupted file systems, bad hard drive sectors, or virus attacks.
• Large database file: If the file is too large, you won't be able to open it, and you'll receive an error message. Additionally, your hard drive might be running out of space.
• Virus attack on the system: A virus attack can impact all your files if your system is compromised.
• Malfunction of Microsoft Office suite: When Access splits a database, it divides it into two files - one containing queries, forms, and reports, and the other holding the backend database with data tables.
• Usage of outdated MS Office service packs: If you haven't updated MS Office service packs for a long time, this could cause issues.
• Incorrect splitting of Access database file: If the database is split using Access but the process is improper, the resulting files may become non-functional or fail to open.

Alright, now that you've read and grasped the causes of the error, let's proceed to the next part – How to resolve the unrecognized database format error.

Fix 6: Convert the Database File to ACCDB File Format

The MDB file format was utilized for Microsoft Access databases prior to 2007. With the release of Microsoft Access 2007 and Access 2010, it was succeeded by the ACCDB file format.

However, users of Access versions prior to 2007 might encounter issues due to this file format substitution. Microsoft Access displays the "Unrecognized Database Format MDB" error when attempting to open files in older formats.

Don’t worry; you can convert the MDB database file produced by earlier versions of Access to the ACCDB file format.

To convert an MDB database file to ACCDB format, follow these steps: 1. Open Microsoft Access: First, ensure that you have Microsoft Access installed on your computer. The version should be 2007 or later, as the ACCDB format was introduced in Access 2007. 2. Create a new blank database: Launch Microsoft Access and create a new, empty database by clicking "File" > "New" > "Blank Database." Give it a suitable name and choose a location to save it. 3. Save the new database in ACCDB format: Once the new blank database is created, click "File" > "Save As." In the "Save As" dialog box, select the location where you want to save the converted database and type the same name as your original MDB file. From the "Save as type" dropdown, choose "Microsoft Access 2007-2019 Database (*.accdb)" and then click "Save." 4. Import tables, queries, forms, reports, and macros from the MDB file: With the new ACCDB database open, click "External Data" in the ribbon menu, then click "Access" in the "Import & Link" section. Browse for your MDB file, select it, and click "Open." 5. Select objects to import: In the "Import Objects" dialog box, check the boxes next to the tables, queries, forms, reports, and macros you want to transfer from the MDB file to the ACCDB file. You can choose to import them as links or as copies. If you select "Copy," the data will be copied and stored within the new ACCDB file. 6. Complete the import process: Click "OK" to start the import process. Access will import the selected objects into the new ACCDB database. Wait for the process to finish. 7. Verify the conversion: After the import is complete, review the new ACCDB database to ensure that all desired objects and data have been successfully transferred. 8. Close both databases: Save any changes and close both the original MDB database and the newly converted ACCDB database. Now, you have successfully converted your MDB database file to the ACCDB format.

Step 1: Launch Microsoft Access.

Step 2: Open a Blank desktop database.

Step 3: Following that, go to the File tab and click on Open.

Step 4: Select the database file you want to convert and open it.

Step 5: You will receive a security warning; click on Enable Content next to it.

Step 6: Next, click on 'File' then 'Save As' and select 'Access Database' under 'Database File Types.' Click the 'Save As' button, give your database file a name, and then click 'Save.'

Open the database and see if the error message reoccurs.

Step 7: Run the Compact and Repair Tool

Access includes a built-in utility called Compact and Repair Database. This tool can be useful when the database file becomes corrupted or its size increases significantly. It helps optimize the file by compressing it and fixing any underlying issues.

However, there are two things you shouldn't overlook before utilizing this tool:

1. The tool might induce a database failure since it is an exceedingly intrusive database operation. 2. If the database file is located in a shared area, make sure to provide all users with instructions to safely shut it down.

Now, follow the steps provided below:

Step 1: Open Access and choose Blank desktop database.

Step 2: Go to the Database Tools tab and click on the Compact and Repair Database button. (Click the Enable Content button beside the Security Warning prompt.)

Step 3: Select the database file that needs to be repaired and click the Compact button.

Step 4: Rename the compact database in the Compact Database Into dialog box, then click the Save button.

The tool will begin repairing queries, indexes, tables, and other data, and it will also compact the database file.

Reopen the database file and see if the error message resurfaces.

Solution 8: Free Up Disk Space

The error "unrecognized database format" might occur when there isn't sufficient hard drive space available. Hence, it's essential to examine your hard drive usage. If you require additional space on your hard drive, utilize a tool like Partition Master to free up space.
