Corrupted save game

[kaszlnikk]

I was in the end of Sweden ironman run, in the war with Commonwealth for last provinces for Baltic Sea achievment in early 1700s and save game got corrupted
I know i should change that save game extension from .eu4 to .zip and i already did it but i don't know how to unpack/compress it
Can someone tell me how to do it?
Backup of that save game unfortunately is corrupted too

An uncorrupted save file can be uncompressed by any zip program(e.g. the compressed folder function in windows) if you change the file extension to .zip.
But what are you hoping to accomplish by unpacking your save file? The files in an ironman save are in a binary format and can't be edited in a text editor and most changes to them will disable achievements. If the game would not be ironman, some minor corruption could be fixed by uncompressing it and editing its files in a text editor. But I don't think that there is any way to fix corrupted ironman saves. In what way is your save corrupted?
My usual recommendation is to regularly create additional backup saves and store them in a different location so that you can go back to them if something breaks your main save and the automatic _backup file.
