opening zip failed i/o error

Post by dingocc »

I see many others over the years have experienced this. For no good reason, my zip is invalid, and I cannot open the zip in Windows either. Finished the session yesterday like normal.
Anyway, the 3 autosaves appear to be valid zips. When selecting / single player / load game only the corrupt save is shown. How to load an autosave, it's possible?

Autosaves should be shown in the load menu. You might want to move the corrupt save to another directory, to see if maybe it's preventing Factorio from reading the rest of the files properly.

Removing the corrupt file did not allow the other saves to show.

Using winrar I have repaired the save and can see the contents. Factorio will not load it as the CRC check fails. As I can get the save/zip contents how do I go about moving the contents to a new valid zip?

I'm good, fixing the 'main' save allow the other saves to appear. Thankfully.
