.ECC File Extension
File Typedvdisaster Error Correction File
What is an ECC file?
Data file created by dvdisaster, a program used for recovering errors in CDs, DVDs, and Blu-ray discs; stores data used for reconstructing unreadable sectors on a disc; requires an error-free disc or .ISO disc image to generate the error correction data.
ECC files are used for safeguarding the data on discs over time, since optical discs have a limited lifespan. Note that the ECC files must be generated from error-free discs first, and then they can be used to correct discs with errors at a later time.
