Input-output error on file saving

[ItsKieran]

So, I’m having a weird issue here. I am making a presentation (.odp) and, yes, it’s using a lot of big image files. The presentation is 2.5GB at the moment. I have lots of space, so that isn’t an issue.

The issue I’m having is that when I try to save the presentation, it tells me this:
Error saving the document :
General Error.
General input/output error.

HOWEVER, this only started just last night. I’ve been working on this for about a week now. It’s been saving to the same directory just fine for ages, and now suddenly it decides to stop working.

The weird part is… it does actually save it. If I make a change, try to save, then it gives me the error, then I close it out and re-open, it tells me the document is corrupted, so I click to repair it, and there’s my file, saved, as if nothing happened.

I’m confused as to why it’s doing this. I’ve seen things about updating - did that, I’m on the latest version, still happening. I’ve seen things about the user profile - tried resetting it and using safe mode, still issue persists. I’ve seen things about Windows Defender - nope, my windows defender doesn’t have the file control setting turned on. I don’t know what to do.

2.5GB at the moment

That is absolutely huge!
I hope you still have your original images somewhere in a directory, then
select Tools > Compress Presentation.

EDIT: I now realise that Minimise Presentation is the same thing! My bad

I don’t have that option under Tools. If this is something you can do in LibreOffice, I think that would be really helpful. I didn’t know you could compress them!

Minimise Presentation

That is what is meant by that!
The above is a translation issue.

When trying this, I get:

Error saving the document:
Write Error.
The file could not be written.

Remove a few of the last images from the presentation and try again.
Alternatively, create a copy of the file, open it, split it in half, and try again—step by step.

Typically, images should first be resized as copies in an external image-editing program (for example, using batch processing) before being inserted into the presentation.

Yes, I can confirm that this worked. Removing images first to reduce the initial file size allowed for the file to save - then I could carry out compression. I will remember this going forward - thank you!
