Lost file
Hi,
I am writing in relation to the posted issue of program crushing and lost files (impossible to re-open).
Since this issue appeared I have started to work in some kind of backup using “save as” option every couple of steps. Unfortunately such an action is time and storage consuming. Every new “save as” consumes about 1GB of disk storage because it generates every time new file + new folder with all allocated data. In addition you cannot stay on 2 files/folders e.g. “A” and mirrored “B” because “save as” is unable to overwrite the file. So it ends up with A01, A001, A0001 and so on.
Last time the program crushed I was able to open fourth file/folder back not a previous one. So there is no pattern which backup file would work again 
Any hint on backup workflow until the crushing issue is sorted out?
Cheers,
Iza
