This article was previously published under Q110968 SUMMARY
When opening a database file (.DBF), FoxPro checks the header for the
following five conditions that indicate corruption in a table:
- Is the record length invalid?
- Record length <= 1
- Record length > maximum record length
- Are there no fields?
- Are there more fields than permitted?
- Is the number of records < 0?
- Is the file size invalid?
- (Start-of-data + the # of records) * rec. length > file size
NOTE: Start-of-data is where the first byte of the first
record begins.
