How to avoid file corruption

[mlaiti]

Hello, hello,
I lost a very long work, because visio file became corrupted and lost a long of time to repair it without success.


It happens many times ... i change my visio from 2016 to 2019, and the problem occurs.
Not systematically, but time from time.

So my question :
Which version of microsoft visio is reliable ?
How can I avoid to lost my files ? (Because of corruption!!)
Are the “cheap” versions of microsoft visio reliable ? I bought it about 19euros(=19dolllars), or should i buy from the official microsoft site ?

Thank you in advance.
