Before proceeding, let&rsquo;s first understand the Access file formats.<\/p><h2 class=\"wp-block-heading\" id=\"what-are-mdb-&amp;-accdb-files?\">What are MDB &amp; ACCDB Files?<\/h2><p class=\"wp-block-paragraph\">MDB and ACCDB are the two database file types used by different MS Access versions. Let&rsquo;s read more about them in detail.<\/p><p class=\"wp-block-paragraph\"><strong>MDB: <\/strong>Short for Microsoft Database, MDB file (file extension &ndash;&nbsp;.mdb) is a database file type used by the legacy versions of MS Access &ndash; 2003 and earlier (till Access 1.0). It stores typical database objects, like queries, tables, forms, and reports.<\/p><p class=\"wp-block-paragraph\"><strong>ACCDB: <\/strong>All latest versions of MS Access &ndash; 2007, 2010, 2013, 2016, 2019, 2021, 2024, and Microsoft Access part of Microsoft 365 use ACCDB (.accdb) as the default file type for creating databases. This file format offers advanced features with improved and optimized functionality. 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=\"why-does-an-access-database-get-corrupted?\"><strong>Why does an Access Database get Corrupted?<\/strong><\/h2><p class=\"wp-block-paragraph\">Corruption in Access database can occur due to various operational and system reasons. Some common causes are:<\/p><ul class=\"wp-block-list\">\n<li>Frequently editing data in Memo fields (Long text fields)<\/li>\n\n\n\n<li>Interruptions like network issues when making changes to data<\/li>\n\n\n\n<li>Jet database engine version conflicts or mismatched service packs<\/li>\n\n\n\n<li>Virus and malware attacks on the system where you&rsquo;ve saved the Access database file<\/li>\n\n\n\n<li>Dissimilar JET Engine service packs<\/li>\n\n\n\n<li>Improper exit of the MS Access application<\/li>\n\n\n\n<li>Write operation conflicts due to software incompatibility, hardware failure, or poor network connectivity<\/li>\n\n\n\n<li>Bad sectors on the storage drive<\/li>\n\n\n\n<li>Large size of the database file (&gt;2GB)<\/li>\n\n\n\n<li>Power cut or abrupt system shutdown<\/li>\n\n\n\n<li>Hardware failure or software bugs<\/li>\n\n\n\n<li>Conflicting plug-ins<\/li>\n<\/ul><h2 class=\"wp-block-heading\" id=\"how-to-repair-microsoft-access-database?\"><strong>How to Repair Microsoft Access Database?<\/strong><\/h2><p class=\"wp-block-paragraph\">When your Access database throws error messages or fails to open, you can use various built-in tools, manual recovery methods, or professional Access database repair software to fix it.

Microsoft Access creates temporary lock files (.<a href=\"https:\/\/learn.microsoft.com\/en-us\/troubleshoot\/microsoft-365-apps\/access\/lock-files-introduction\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">LDB file<\/a> for .mdb files and .laccdb for .accdb files) when you open or access a database for shared use. The lock file has the same name as that of the primary file but with the .ldb \/.laccdb extension. This helps in keeping track of all active users accessing the database.<\/p><p class=\"wp-block-paragraph\">When the last user closes the file, this lock file is deleted automatically. But, it might not get deleted if the user doesn&rsquo;t have delete permissions to the Access database (.mdb) file for that network or the database is corrupt. You can delete the .ldb file or .laccdb file to remove the lock on the .mdb file if you want to recover the data from that file.<\/p><h3 class=\"wp-block-heading\"><strong>Method 4: Use Jet Compact Utility (Deprecated Tool to Repair MDB Files)<\/strong><\/h3><p class=\"wp-block-paragraph\">The <a href=\"https:\/\/www.stellarinfo.com\/blog\/repair-ms-access-database-file-recover-data\/#step-3-use-jet-compact-utility\" target=\"_blank\" rel=\"noreferrer noopener\">Microsoft Jet Compact utility<\/a> (JETCOMP.exe) is a deprecated tool that was used to repair corrupt MDB files. It is incompatible with modern database files (.ACCDB). New Access versions use the Access Connectivity Engine (ACE) instead. To repair a corrupt .ACCDB file, you must run the \/compact switch via the Microsoft Access (MSACCESS.EXE) command line.<\/p><h3 class=\"wp-block-heading\">Method 5: Remove all Compiled VBA Codes from the Database<\/h3><p class=\"wp-block-paragraph\">Decompiling VBA codes reverts compiled codes to the source code. It helps to recover corrupt database. This can be done by using this command line switch:<\/p><pre class=\"wp-block-code command_container\"><code><strong>C:\\Program Files\\Microsoft Office\\Office\\MsAccess.exe \/decompile C:\\DatabasePath\\FileName.mdb<\/strong><\/code><\/pre><blockquote class=\"note_alert\">\n<p class=\"wp-block-paragraph\"><strong>Note:<\/strong> <em>You may need to change the path shown above for MsAccess.exe if you installed it in a different location.<\/em><\/p>\n<\/blockquote><h3 class=\"wp-block-heading\">Method 6: Import Corrupt Database Objects into a New Database<\/h3><p class=\"wp-block-paragraph\">Try importing affected database objects into a new Access database file. It helps recreate the structure of the corrupt file, with its objects. You can copy\/import your data into a new blank database by following these steps:<\/p><ul class=\"wp-block-list\">\n<li>Open MS Access and create a new database file. To do so, click <strong>File<\/strong> &gt; <strong>New<\/strong> &gt; <strong>Blank Database<\/strong>.<\/li>\n\n\n\n<li>Next, click the &lsquo;<strong>External Data<\/strong>&rsquo; tab and select &lsquo;<strong>Access<\/strong>&rsquo; on the &lsquo;<strong>Import &amp; Link<\/strong>&rsquo; menu.<\/li>\n<\/ul><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"826\" height=\"339\" src=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2015\/04\/Access.png\" alt=\"select Access on the Import &amp; Link\" class=\"wp-image-192003 apply-gradient-on-post-images\" srcset=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2015\/04\/Access.png 826w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2015\/04\/Access-300x123.png 300w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2015\/04\/Access-768x315.png 768w\" sizes=\"auto, (max-width: 826px) 100vw, 826px\" \/><\/figure><ul class=\"wp-block-list\">\n<li>The &lsquo;<strong>Get External Data &ndash; Access Database<\/strong>&rsquo; dialog box is displayed.
