Error 9997 Can't open OpenEXR files

[Petr Holusa]

Hi,

Not sure what this suppose to mean. I have collected project from my working original project. After checking collected package I got this message. 

[ToolfarmJP]

I guess two possible causes. One is the permission of the folder. You check everyone can open it. The other is the exr file is corrupted. You check the file can be opened by other applications like Photoshop.

Thanks for reply. I noticed that AE somehow doesn't like the file NAME from C4D/Redshift. I checked fith some file name checker and it said it has to be renamed which was surprising. So I batch renamed the files and it works. Even win explorer said my files has long names but I don't think so.

I have changed the names but still have the same problem. Any advice ?

Same problem here! Any solution?

I had success changing the file location to be on my root drive, not an external dropbox directory. Really annoying, but it worked!

ToolfarmJP is correct this is a file permission issue. It looks like you are using dropbox on an external drive. I ha s spoken to Adobe at great lebgth about this and they unfortunately dont support external hardrives. I would reccomend resetting the file permissions on the drive although that didnt work for me. If you copy the files to your desktop they sjould work, if you need them on the external drive then I would copy them back on and it should the problem it. Hopefully Adobe will start supporting external drives but as of a couple of months ago they ahve no intention to.

What?  There's no way this is true.

The same error occurred when exporting the EXR. There is another commonality, and that is that I was also managing my project files in Dropbox.

I found that when I exported the EXR on Dropbox, the error occurred quite often.

The solution was to export to local storage that is not Dropbox, and so far no errors have occurred.

By the way, I have not seen any errors except for exporting EXR.
For example, exporting Tiffs and pngs is not a problem.
No error occurs when reading EXR files on Dropbox.

The error occurs only when exporting EXR to Dropbox.

Interesting. I use dropbox especially for backup for ongoing project. Good to know. Thank you.

It's the length of the file path, reducing the length of the path will fix this. Running it on Dropbox/hard drive/network drive will still work. Not sure the exact max length AE will read, but I'd try reducing the length of your folders and file names

@jacks42063454 You are a Brilliant one man !

Im years late, but I´m pretty sure this is the problem. If you have very long paths After Effects wont be able to open that files. Its very weird because sometimes it tells you why the problem, but in this case doesnt reference the problem to path length
