Let&rsquo;s read more about them in detail.<\/p><p><strong>MDB<\/strong><\/p><p>Short for Microsoft Database, MDB file (file extension &ndash; <strong>.mdb<\/strong>) is a database file type used by the legacy versions of MS Access &ndash; Access 2003 and earlier (till Access 1.0). It stores typical database objects, like queries, tables, forms, and reports.<\/p><p><strong>ACCDB<\/strong><\/p><p>All latest versions of MS Access: Access 2007, 2010, 2013, 2016, 2019, 2021, 2024 and Microsoft Access (part of Microsoft 365) use ACCDB (<strong>.accdb<\/strong>) as the default file type for creating databases. This file format offers advanced features with improved and optimized functionality.<\/p><p>With an improved database security model, it supports the security validation of DB files, with the major advantage being that both MS Outlook and SharePoint trust this validation.<\/p><h2 class=\"wp-block-heading\" id=\"how-to-convert-access-database-file-format-from-mdb-to-accdb?\"><strong>How to Convert Access Database File Format from MDB to ACCDB?<\/strong><\/h2><p>As per <a href=\"https:\/\/support.microsoft.com\/en-us\/office\/which-access-file-format-should-i-use-012d9ab3-d14c-479e-b617-be66f9070b41#__toc306205042\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Microsoft&rsquo;s documentation<\/a>, you can open MDB files using any new version of MS Access (2007 or later). However, you won&rsquo;t be able to use some functionalities that require the .accdb file format. So, if you want to use new features, you&rsquo;ll need to convert MDB to ACCDB first.<\/p><p><strong>Here is how you can do this by using Access 2007 or newer version:<\/strong><\/p><ul class=\"wp-block-list\">\n<li><strong>Launch<\/strong> MS Access.<\/li>\n\n\n\n<li>Choose the <strong>Blank desktop database<\/strong> option.<\/li>\n<\/ul><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"491\" height=\"294\" src=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2015\/04\/Blank-desktop-database.png\" alt=\"Choose the Blank desktop database option\" class=\"wp-image-191989 apply-gradient-on-post-images\" srcset=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2015\/04\/Blank-desktop-database.png 491w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2015\/04\/Blank-desktop-database-300x180.png 300w\" sizes=\"auto, (max-width: 491px) 100vw, 491px\" \/><\/figure>\n<\/div><ul class=\"wp-block-list\">\n<li>Give the new database file a name and click on <strong>Create<\/strong>.<\/li>\n<\/ul><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"598\" height=\"290\" src=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2015\/04\/Create-a-new-database.png\" alt=\"Create Blank destop database\" class=\"wp-image-191990 apply-gradient-on-post-images\" srcset=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2015\/04\/Create-a-new-database.png 598w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2015\/04\/Create-a-new-database-300x145.png 300w\" sizes=\"auto, (max-width: 598px) 100vw, 598px\" \/><\/figure>\n<\/div><ul class=\"wp-block-list\">\n<li>Once the new database file opens, click on <strong>File<\/strong> &gt; <strong>Close<\/strong>.<\/li>\n<\/ul><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"136\" height=\"479\" src=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2015\/04\/choose-save.png\" alt=\"click on File &gt; Close\" class=\"wp-image-191991 apply-gradient-on-post-images\" srcset=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2015\/04\/choose-save.png 136w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2015\/04\/choose-save-85x300.png 85w\" sizes=\"auto, (max-width: 136px) 100vw, 136px\" \/><\/figure><ul class=\"wp-block-list\">\n<li>Again, click on <strong>File<\/strong> from the ribbon.
