>Thank you Jim. But, it is not incredible that an utility doesn't exist to fix this type of problems? This library is quite big and I had just made regrettably important changes before it was damaged... in any event I thank you.

Jose,

No it is not incredable that no such utility exists as the structure of the VCT is such that it is not possible to discern what it should be b from what it is. A VCT going bad is similar to having the FAT on your hard drive get corrupted, there is no way to recover except for from a backup.

The VCX has a pointer to where in the VCT the contents of a certain field for a certain record begins, from there there are pointers from each entry to the continuation of that entry. If these pointers get out of whack there is really no way to recover them, and the pointers being out of whack is what the corruption causes. This is not the same as corruption in a DBF (VCX) as in these fiels there is an inherent structure that can be repaired and much of the data can be recovered.
