If your access database fie is corrupted and you are searching for how to repair it, then I would like to suggest two way for repairing it.
1. Use "Compact and Repair" feature to repair corrupt MS Access database file.
2. Use 3rd-party access file repair tool.
Both methods can be applied for repairing and recovering corrupt or damaged access database file. Bit I recommned 3rd-party tool because it is very easy to use and reliable. There no chance to loss data. 

Features of Accees Recovery Tool:

• It repairs ms access MDB and ACCDB files
• Restore tables, macros and other items from Access file
• All data are recovered in exact shape without alterations
• Show preview of items before recovery, to reselect tables
• Provide options to export file with schema or schema with data
• Repair oversized corrupted Access database
• Supports Windows Operating System versions such as Win 8, Win 7, Vista, XP and Previous version
