DBF Repair - How To Recover DBF Files

by social2 In reply to corrupted DBF file


It is impossible to repair DBF files without using a good DBF repair program. The file needs to be deeply studied, and the data within re-organized making ir readable to a regular DBF reader. The data must also be studied for differences between which sectors of the file are 'newer' than the others. This is usually done by looking at the date and time stamps on the data. If this is inconsistent with the data, then it indicates irregular saving, or errors during the save. This is, as is obvious, most common in corrupt data which is a result of incorrect saving. A good DBF repair software should be able to go through the given file, into the unstructured data, and place the related data packets together where they belong. This restructuring allows a standard DBF file reader to understand the data again and open the file normally.
Once the file is repaired and the data restored, it is recommended to open the file again and save it as a different copy on another medium of storage. This will ensure that you have a non-corrupt copy of the file as backup and don't have to go through the DBF repair software over and over.

corrupted DBF file

by GavinNichols In reply to corrupted DBF file

DBF file can not physically be larger than 2GB. This system limits even FoxPro, and the format DBASE.
The only way - is a manual analysis of information as a plain text file. Most likely, there are "stuck" some "tail", which must be cut off.
But with old stock you can try it.
Can help?
para n_f
private all like mas
if! '.DBF' $ Upper (n_f)
n_f = trim (n_f) '. dbf'
if! file (n_f)
h = fopen (n_f)
if h = -1
retu .f.

funct cnzap
