[GUI Plugin] KindleUnpack - The Plugin - Page 36

DiapDealer · 08-13-2025, 07:16 PM

The main error seems to be that a file/folder name is not being found:

/Users/thomas/Desktop/unpack/MOBI-The Science Book_ Big Ideas Simply Explain - Dk.mobi

The 2nd error is in the error handling for the 1st error. I've fixed something similar in another KindleUnpack plugin function in the past. It should be easy enough to fix here, but unless I can replicate that "No such file or directory" error, I'll have trouble tracking the initial error down.

Have you tried using the standalone KindleUnpack to try and split that Kindle Previewer created mobi? The problem could be upstream in KindleUnpack proper rather than the plugin.

Can you get me an example of a Kindle Previewer-built dual format Kindlebook that this plugin fails to split? Upload it somewhere and send me a link via PM if copyright is an issue.

For what it's worth: I released a new version that fixes the error-handling bug. And until I can get a sample of KindlePreviewer-created content that won't split properly, I've allowed either portion of the split process to fail (with a warning) without terminating the plugin entirely.

If you're not having any trouble, there's no real reason to update.

Only to report:

Got the following

unpacking this (perfectly working) dictionary referred in this mobileread thread

By curiosity only, I wanted to inspect the inflections. Beyond the obvious, no need to spend too much time on debugging. Thanks.

I think that error places the problem in the upstream standalone kindleunpack core files rather than the plugin. But I'll take a look.
