File is not recognizable, unable to read, file cannot be accessed, out of memory errors…these are all signs that a file has been corrupted and can not be used any longer. Files are corrupted by power failures, network interruption, viruses, and application errors. It is very common for file information to get lost and be unrecoverable.
At least it used to be, with the ever advancing technology more and more programs are being developed to help recover files. I found one resource to help repair files that have been compromised.
