Recovering Corrupt Dbf File In Case Of Insufficient Memory

In the Windows systems, a paging technique is used when there is some memory issues with some applications

. In this Virtual memory technique, additional memory is provided to applications through virtual addresses that are being mapped to physical addresses on the hard disk. However, if it is not done perfectly, then it may cause corruption in the DBF file, which can also result in inaccessibility of FoxPro. You should try out appropriate methods to repair DBF file failing which you should go for a DBF file repair software.

Consider a scenario wherein you are working on an software application in MS Visual FoxPro 6.0 for your college project. You open MS Visual FoxPro but it fails to open and exits after displaying few error messages. These messages could be either of the following messages:

Insufficient memory

Not enough memory for application (minimum 2187264 required)

Not enough memory for application (minimum 2158592 required)

Cause:

The root cause of such abnormal behavior of FoxPro is that the virtual memory is not sufficiently available to start FoxPro. Such memory issues can also be caused due to corruption in the DBF file.

Resolution:

To overcome such problems, you should need to perform the following steps:

Increase the size of the paging file: You should look to increase the size of the Windows Swap file to resolve the virtual memory issues. Restart the system and check if the issue is appearing again.

Reduce the expandable memory: If you are using an EMS (Expanded Memory Specification) emulator, then reduce or remove the amount of memory that it provides.

Reduce the size of the disk-caching software: If you are using a disk-caching software, then reduce its size as it may be causing the memory issues.

Restore DBF file: You should try to restore the FOXUSER.DBF file by renaming it in the command prompt using the following syntax:

RENAME foxuser.dbf foxuser.dbk

Restart FoxPro. The Foxuser.dbf file will be renamed when you restart FoxPro.

These aforementioned methods would be able to repair DBF file and start MS Visual FoxPro. However, if it is not the case then there is an immediate need to perform DBF recovery using a professional DBF file repair software. These tools ensure best results while using highly effective repair algorithms in very rich user interface.
