It has been seen that Microsoft Access databases grow in size and therefore uses unnecessary disk space. Database files can grow quickly as you can use them and sometimes impeding performance. Repeated modification to the database files may sometimes result in data corruption. They can also become corrupt occasionally or even they can de damaged. This risk increases when the database is shared by several users over a network. So it is better to run periodically the compact and repair database tool so that you can ensure the consistency of your data. However you can make use of a Compact and Repair Database command in Microsoft Office Access so that you can prevent or fix all such problems.
However if some serious problems occur in between your working in Access file and if access tries to recover it then you might get a message that the repair operation was cancelled and so you should compact and should repair the file. When you compact Microsoft access file that is located on a volume which sues the NTFS file system, then access removes the entire existing file and replaces it with the compacted file. After that it applies the default file permission to the new file.
Database files can become corrupted:
The database files can become corrupt or gets damaged in certain circumstances. When the database file is shared over a network and when several user works directly with the file then the file has a little bit risk of becoming corrupted. This risk can be greater when users frequently edit the data in Memo files and after that the risk grows over time. You can solve this risk by using compact and repair database command. This type of corruption results from a problem with a visual basic for applications module and does not pose a risk of data loss.
Rarely database file corruption does result in data loss. This loss is limited to the last action of one user which is single change to data. When the users start to change data and then the data is interrupted, for instance, due to network service loss, access marks the database file as corrupted. This file can be repaired but some data may be missing after the repair is complete.
How to repair?
When users tries to open a database file which is corrupted, then you are prompted to let access automatically repair your file. You can also manually use the compact and repair database command to repair and open a corrupted database file. If access completely repairs t5he corrupted file then it will display a message which will state that the repair was successful and so you can now check the database contents so that you can be sure that everything is ok as it should be. If access is not successfully completed or partially successful them it will track all the database objects which could not repair and so you can think what you should need to recover from a backup.
If you are a single use than you can set a database option which causes the compact and repair database command to run automatically each time after you close a particular database. And if you have a multi-user database then it is not possible because it can momentarily disrupt the database availability.
steps to repair the issue:
Step 1:Download and install Stellar Phoenix Access recovery software.
