Why I get this error message? How figure can be corrupt?

I try to open a figure and I get the following error

Error using load
Unable to read MAT-file D:\stelios phd files\DesMoines\karadokei\assume.fig. File might be corrupt.

Error in matlab.graphics.internal.figfile.FigFile/read (line 31)
hgDataVars = load(filename, '-mat', '-regexp', '^hg[M]');

Error in matlab.graphics.internal.figfile.FigFile

Error in loadFigure (line 31)
FF = matlab.graphics.internal.figfile.FigFile(fullpath);

Error in openfig>localOpenFigure (line 69)
    h = loadFigure(filename, visibleAction);

Error in openfig (line 40)
figOut = localOpenFigure(filename, reuse, visibleAction);

Error in experiment (line 5)
hFig = openfig('assume.fig')

Any reasons for this?

Seems to be a recurrent theme...

Unfortunately, don't see any real permanent solutions other than revert to a previous working copy or update version seems to have succeeded at least on one occasion...

The file is corrupted. There is no chance that the forum can fix the problem for you.

You have to restore the former version of the file from your backup - perhaps Recent Versions under Windows? All changes you have done since the last backup are lost.

Do you remember what you have done with the file before it got corrupted?

Problem fixed Jan. I found a back up of the fig. I posted this question wondering if there was a way to fix or restore corrupted files.

It depends on how the file was damaged.
