Critial error in cubase (can't save project / save as new)

Cubase
1

Hey guys,

All of a sudden I have a message:

“The project could not be saved, because:

An unexpected error occured. The system’s description is: Too many open files No new project could be created.

I press OK and every time I try to hit command+S I get this message.

  1. How can it be solved?
  2. What caused it?
  3. Where are the technical specs / guidelines that one could follow to avoid this from ever happening?

Please advise.

Thanks!

Hi,

which Cubase version and OS are you on?
Are you running any background processes like OneDrive which might prevent Cubase from writing files?
How big is your project? Do you have enough disk space on that particular drive?
Have you tried “Save As” under a different location, too?

Hi,

My setup:

  • macOS Seqoia 15.6.1
  • Cubase 13.0.55.328 (according to get info on Cubase in Mac)

As for your questions:

  1. I do have a Google Drive app that auto syncs everything and it was not responding when I searched for it, however I force quit it and the error message continue in Cubase (and the Google Drive app relaunched and it’s now working fine).
  2. The project’s folder is 31.9 GB for 8,051 items. I have > 1TB to use on my computer

  3. I tried saving the project (.cpr file) to another location - when going Save As the Folders browser opens up, and then no matter what’s the chosen destination (even tried with Desktop) this error message pops out again.
    1. As previously stated, just doing “save “ pops the message immediatly

The folder structure is:

  • Main Folder (for let’s say Song A) (31.9 GB)
    • Song A
    • Audio folders (both recorded on Cubase and other Audio files)
    • Edits
    • Images
    • Many .cpr and .bak files (different versions and backups)
    • Mix Phase folder (10 GB)

      • Many .cpr and .bak files **including the .cpr in question (**10-14± MB)

      • Audio folder for pre-mixed stems

      • These 3:

Any more information?

I’ll also ask - is there any channel for official technical support from Steinberg for these cases?
Perhaps @Martin.Jirsak will know? (Sorry for the tag but I’m really in a pickle here)

Thanks!

Hi,

How many projects do you have open simultaneously, please?

Where are your projects stored (what are the parent folders)?

Could you try to go for File > Backup project, please?

Hi Martin,

  • I had 2 open projects
  • This is the full path - /Users/royteicher/Desktop/Music Production/Cubase Projects/0.1 My First Album/1 מפלצת הגרוב/Post Mix Stems/מפלצת הגרוב מיקס 5.4.cpr’

I closed the project, relaunched it and said yes to ‘open more recent backup’ - then the .bak file renamed itself to .cpr with a suffix of -01.

Tried to save it and got that error message again.

Then did File > Backup project and continue with the default setting and now I could save it!

So thanks for the tip, I’m up and running with it, but I am still really curious to know what could be the cause of all this and how to avoid. File >Backup project was a nice workaround but I’d love to not experience this again lol

Hi @Fried_Onion,

Thank you for sharing.

Did you back up your project into a similar folder and with a similar name? I’m going to investigate the non-English symbols. I know, Cubase is tested with multiple different symbols (especially Chinese and Japanese, as these are the officially supported languages), but there might be a symbol set which might lead to some unknown issues.

Again, thank you for sharing!

Hi @Martin.Jirsak ,

You’re most welcome, thank YOU!

These are Hebrew letters, I know it’d be best practice to have all project names in English, however I’ve been using Hebrew for the project’s titles for years and never encounter a problem.. until now I guess :slight_smile:

By default, many .bak files are saved to the same location. When the latest saved work properly - I actually used the exact same number - only with 5.5 instead of 5.4 (the Hebrew words stayed in place)

BTW - Where can I get the official documentation regarding folder structure / .bak files location defaults / etc? I’d love to save my projects more profesionally and with more confidence that I’m doing the right thing.

Well, just returned to the project and I have some unfortunate news..

I played it - heard the playback for a fragment of a second and it stopped.

Currently, all audio events are BLANK except random moments.

And when I tried saving the project again, this time to an all-English title, I got this message:

Hi,

Could you trigger the macOS hardware tests? I would focus on the drive and RAM tests. Just in case…

10

Do you refer to this - Use Apple Diagnostics to test your Mac - Apple Support (IL) ?

I really prefer not to update my macOS for the sake a test.. are there any other directions we can explore?

11

Hi,

You can run these kind of tests at any macOS version.

Instead for me, when I want to save the project, instead of saving it, the save as dialog opens with the Macintosh HD folder. The save function does not work anymore or I am doing something wrong?

Hi,

For the very 1st time, the Save As is called instead of Save. Once you save it, Save should be in use, if you press Ctrl/Cmd+S.

Thank you and you are right! The problem is other: when the save dialog opens will not open in the project folder, instead on Macintosh HD. :frowning:

UPDATE: I think was a problem with the folder, cause I created a new one and the problem solved
