Hello Enzo,

The first thing I would do it to turn on automatic backups.   If you go  
to the main Configure KMyMoney page, select the Global (first) tab, the  
second section is "Autosave options."  Make sure the last item - number  
of backups to keep is not 0.  I have it set to 10.  This means every  
time you save the file, it moves the previous file by adding "1~" to  
the end, and moves the old "1~" file to "2~" and so on.  If you save  
often, that is enough, but if you might forget to save, you can tick  
the checkbox above "Autosave when file is modified upon close."  Then,  
every time you quit KMyMoney, look at the files to be sure they are  
present and don't change size suddenly by very much.

This is also a place where there are many linux utilities which would  
help be sure the saved files are valid.  One thing you might be able to  
do is to open the folder where the files are in Windows Explorer.   
Right click on one of the files and select "properties."  I'm not  
certain, but it should probably tell you it is gzip compressed data.   
If it does say this, then if all they bytes ever again become zeros, it  
will probably say unknown or data, since the specific bytes that  
indicate it is compressed are no longer present.

If, for example, you use enzo.kmy, and at some point, enzo.kmy is  
invalid, you can try copying (keep all the original files until you are  
sure you have a good copy) enzo.kmy.1~ to enzo2.kmy and then try  
opening that file with KMyMoney.  If it works, then continue using it.   
If if is bad, try with enzo.kmy.2~, and so on.

In terms of trying to find how the file got changed to all zero's, that  
is very difficult.  What Thomas said, that it looks like a "wipe to  
zero for security' feature, might be true if you are using any security  
software, such as an anti-virus, which for some reason thought your kmy  
file looked like a virus.  If you do use some security software, you  
might try making it scan your kmy file, just to see if it has a  
problem.  You can also look at any log of that program to see if it  
thinks it cleaned up any virus or malware.  If it did, then you need to  
report it to wherever you got that software.  However, that doesn't  
seem very likely, so the best you can do is just to keep backups.
