How to repair a damaged Visio file?

Question

Data recovery

Visio cannot open a corrupted file.
Is there any way to restore it?
Is there any way to extract information from the drawing of a file?

Answer 1

I registered only in order to help those who found themselves in a similar situation, in general the solution is this:
Above they suggested that you need to look towards ZIP and were right, just open the damaged VISIO file with Winrar -> operations -> restore archives and perform the recovery procedure.
It worked for me with all files. Good luck to all

Answer 2

Try to view the content using the Python console utility OLE Toy

OLE Toy is a set of Python scripts to parse and view contents of various
binary file formats. Originally OLE Toy was developed for
reverse-engineering of Microsoft Publisher file format, but later support
for more of them was added, partially written from scratch, partially
moved from our earlier work.

Useful information will be in which version of the Visio format the file is saved.
