Lost indesign files

[...] It has been regularly autosaved and indesign hasn't notified me of any missing or corrupted files.

Unfortunately, there is no "autosave" in InDesign.

You say it was regularly autosaved, but did you actually SAVE it? That's not the same as autosave.

Hi @._natalie_.:

I know this is stressful but InDesign doesn't delete files so let's try to figure out what happened. Sharing additional details would be very helpful: 

• What does "It has been regularly autosaved" mean? Are you referring the about-every-minute mini-save to the InDesign Recovery folder? Those temp files are deleted when we save so we typically only access them after a crash. Did InDesign crash with the file open?
• If you did crash, you may not see the list of recent files on the Welcome screen—which makes some people think the files are gone. You just need to locate them on your drive and reopen them manually. 
• Letting us know where the files were saved will also be helpful, as will seeing what error message comes up when you try to open the file in the recovery folder.

I'm really not sure what else I can do.

Don't you know where you saved your files? Did you try to find them using file explorer (Windows) or the Finder (Mac)?

@._natalie_.

Unfortunately, if you don't have a proper backup copies...

Hi @.natalie.,

Just to clarify, are you unable to find the entire document, or is the file there but missing its content (like objects from the spreads)?

Also, were your files saved locally on your computer, an external drive, or Creative Cloud? Could you try searching for the file name in your system’s search bar to see if it may have been moved? Additionally, could you share your InDesign version and OS details?

Looking forward to your update.
