Failed to recover a faulty DBF file

Recovery Toolbox for DBF may be able to recover your corrupted DBF file.

Reasons for unsuccessful DBF file recovery

Possible reasons why DBF Online Recovery Service was unable to recover your corrupted Microsoft FoxPro (DBF) file:

Here is a list of the most common reasons why the online DBF (FoxPro/dBase/Clipper/1C) recovery service may not be able to handle a damaged file:

1. The file is not actually a DBF file. The file has a .dbf extension, but the content and structure inside the file are not a DBF table.
2. The file size is 0 bytes.
3. The file consists of 100% zero bytes or almost all bytes are zero.
4. The DBF header is corrupted (broken service fields).
5. Incorrect number of records in the header (does not match the actual number).
6. Incorrect record length in the header.
7. The field table in the header is damaged or truncated.
8. The code page (Language Driver) is not specified/corrupted/unsupported.
9. The file type/version (dBase III/IV, FoxPro, VFP) is not recognized.
10. Unsupported field types encountered (e.g., OLE, General, Variant).
11. Fields have incorrect sizes, e.g., negative length.
12. The file contains long tails of foreign data and is filled with garbage data.
13. Records are partially overwritten with zeros or random bytes.
14. The record deletion map is damaged (flag 0x2A/0x20), which breaks the layout.
15. Internal offsets have jumped beyond the file boundaries.
16. The file is encrypted or password-protected. The service does not work with encrypted data.
17. The file is encrypted after a ransomware attack.
18. The level of fragmentation damage is too high and there are no reference structures.
19. There were download errors: connection break/timeout/incomplete file transfer.
20. The file was downloaded in compressed form without unpacking, for example, .zip as .dbf.
21. Multi-user lock conflict: the file was unloaded on the fly during recording.
22. Incompatibility with the 1C version of the structure (non-standard fields/metadata).
23. The DBF has an outdated, rare format variation.
24. The DATETIME/DOUBLE/INTEGER fields contain invalid values that break the parser.
25. Auto-numbering/system flags (VFP) are damaged, preventing parsing.
26. Non-standard COLLATE/locales (FOXCASE, etc.) are damaged and not supported.
27. Mixing of CR/LF and binary garbage within records.
28. Inconsistent record boundaries, incorrect shifts of one or two bytes throughout the file.
29. Presence of very long/broken field names that exceed the allowed range.
30. The field table does not end with the 0x0D marker.
31. File from a network/cloud folder with lazy synchronization and not fully downloaded.
32. Access rights error when reading the file because the antivirus blocks the reading of temporary files during recovery due to the presence of malicious code.
33. This is not a single table, but part of a complex solution (such as 1C/old FoxPro), where additional related files/directories are required.
34. Due to physical damage to the media (bad sectors, broken flash drive/disk), the file contains blocks of invalid data.
