We test your possibly corrupt files

In case you think your file suffers from corruption you may send us the file for a test. Please note that we do not check for programming faults or wrong field (or other elements) definitions.

Please send your problematic .fp7 or .fmp12 file in .zip format to winfried@fmdiff.com, or provide a download URL.

The file must meet the following conditions:

• The File is NOT recovered, cloned, or saved as a copy, after the discovery. Only the unmodified damaged file is of any use (unless instructed by us otherwise).
• If you are able to create a Clone of the damaged file(s) that shows the exact same symptoms, you can use this Clone instead.
• A description of the malfunction of the file is included.
• An earlier fully functional file (backup, clone) is required to restore the access privileges.
• (No login/password or dependent files are required, unless necessary for specific tests. Any data contained will be kept confidential.)
• Files MUST be zipped before submission. Zipped sizes up to 50 MB may be emailed. If you need assistance submitting the file(s) please contact us.
• In case you send a Clone, please make sure you open it once on a machine with the correct locale settings (date, time, number format, language, etc.). This is necessary to apply these settings to the repaired file.

After testing the file we will report back what we have found. Usually these are the possible results:

• The file can be repaired, what is damaged, how much time it will take and what it will cost.
• The file is damaged beyond repair

If we can't repair the file, nothing will be charged!

In case it can be repaired AND you agree to have it repaired, we will charge what has been offered.

At this point you have to provide:

• The complete postal street address, landline phone, and email for the invoice.
• The VAT-Id (if applicable)
• You should be prepared to pay via PayPal. Delivery of the repaired files after receipt of payment.

Repairing Access Privileges typically is US$ 300 per file or per 500 MB (whichever is more) and will take one or two days. EU residents will be charged € 250,-, if they provide a valid VAT-Id, otherwise, as well as German residents, will be charged an additional 19 % VAT, regardless.

How far can we go?

The most complicated case we were able to solve up to now:
A file with about 6000 records suddenly had just one record left. The records inside the file were in fact all gone, but the index of the fields still existed. Since most of the fields were indexed we could recreate the records from the index. The difference to the original file was: all words were lower case and data beyond 100 Bytes of a line in a field was just added as words in alphabetical order, but it made sense to the customer. Numbers, dates, times, and timestamps were restored to their original value.
