Adobe InDesign may not support the file format... but was opened 2 hours ago

This is probably due to the fact that InDesign 2021 was just released however I had a file open literally two hours ago and is now unable to open in both 2020 and 2021.

It was created by myself in InD 2020 and I've been working on this certain document for the last week, through the use of a USB, does anyone have any suggestions?

I may.

Go to Finder, navigate your way to the file in question, then Option-click/right-click on the file in question. In the pop-up context-sensitive menu, choose the Open With command. I'll just about betcha that it isn't set to open with InDesign CC2021 as the default. If you click on that option, I'll also betcha it finally opens for you.

Now, how to fix it: in Finder, click once on the file and press the keyboard shortcut Cmd+I to open the Get Info dialog box for your file. Change the default to InDesign CC2021, then choose to make all files of this type open with InDesign CC2021 and you should be past the problem ... for InDesign documents. You'll want to do the same with InDesign templates (.indt), book (.indb), library (.indl) and InDesign interchange format (.idml) files too.

Hope this helps,

Randy

This fix did not work for me - also now it seems to have spread to some of my pdf files too. I have been transfering files between my home PC and my work Mac but have onlt had this isssue in the last week or so. I made some files three days ago on the Mac and can now not open them. I get the "Cannot open the file ###. Adobe InDesign may not support the file format, a plugin that supports the file format may be missing, or the file may be open in another application."

None of these things are happening. It is literally same computer, different day - now updates, no deletions?!

Help.

Tried the above change and the associuation was fine.

Are you using a Windows computer?

If you are, turn off the Preview Pane in your File Explorer window. When Windows shows you the file preview, it doesn't open the file, But as far as Windows considers it, the previewed file is open. Shutting off the Preview Pane eliminates the problem entirely for PDF files, and if you're using file previews or icon (not list) views, can fix the problem with InDesign files too.

Hope this helps,

Randy
