File recovery utility for less common file types?
Posted by Ian R on March 8th, 2008


Hi

I've had good results using a particular file recovery program but it will
only search for standard files types i.e. doc, txt, generic picture formats
etc etc.

Are then any recovery utilities which can be instructed to look for a non
standard extension or part of a file name which isn't a standard file type?

Thanks for any info

Ian

You appear to be using a recovery program that works on signature
alone. A signature on it's own will not regenerate a file name,
though it can be possible to create a file name based on meta data
within the file. This signature only recovery mode should be
considered the last resort for recovery unless you just want photos /
jpegs recovered.

You don't mention the type of non standard files you want to recover.
Some may be posible, and others may have no recognisable structure, or
header to search for. Doing a straigh search for a signature may also
produce false positives, ie when the program thinks it has found a
file start, when in fact it is still in the middle of a good file.

There are some programs that do allow you to enter search strings, I
have never personally evaluated any.

For better recovery, and it does depend on the failure mode, you want
a program that will work on logical recovery, based on existing
filenames, directories etc. The file type to be recovered is then less
important. Again, depending on failure mode, and operating system,
this may also take care of the problem that some files that may be
fragmented.

Oh, what exactly makes you think that.

My guess that you are using a program based on signatures is because
it only searches for standard file types. If the program was using
directory information, then the file type would not be important. To
the operating system, generally speaking, a file is file, be it a
picture, a database, or unique data file.

My other assumption (also a guess) is that you are using Windows.

Are my guesses correct, or way off the mark?
