fixdat files are created by using the "Generate Reports" button. The fixdat files will appear in the "Reports" folder by default - but when you click that button, ROMVault will prompt you with at dialog that lets you select where to put the fixdat files. You may want to create a "Reports" folder in "M:\Tosec", that is, make the folder "M:\Tosec\Reports") before you press the "Generate Reports" button.
The OP was trying to fill other people's fixdats.
It looks like you are trying to make fixdat files.
Maybe you should have made a new topic for your question?
