Big translation files

Posted on by IĆ-15061320-0

Hello,
I'm just wondering how you handle translation files (.xlif) that have almost 100,000 rows.
VSCode, with extensions like NAB or Xliff, works too slowly.
Apps like Poedit are fast but can break the XML.
I wonder how Microsoft handles translations for their apps.
Thank you!

Hello,

Microsoft provides several tools and best practices to manage these files efficiently:

Dynamics 365 Translation Service (DTS): This service can help you manage and translate large XLIFF files. It supports batch processing and can handle large volumes of text, ensuring that the translations are accurate and consistent.

Document Translation in Azure: This feature of the Azure AI Translator service allows you to translate entire documents, including XLIFF files, while preserving their original formatting. It is designed to handle large files and batches of documents, making it a suitable option for extensive translation tasks.

Optimizing VSCode Performance: While VSCode with extensions like NAB or Xliff can be slow with large files, you can improve performance by:

Increasing the memory allocation for VSCode.

Using the "Incremental Build" setting in the AL Language extension configuration to reduce the load during the build process

Best Practices for XLIFF Files:

Splitting Files: If possible, split large XLIFF files into smaller, manageable chunks.

Regular Backups: Keep regular backups of your translation files to prevent data loss.

Validation Tools: Use XML validation tools to ensure that the XLIFF files are correctly formatted and free of errors.

By leveraging these tools and practices, you can handle large translation files more efficiently and avoid common pitfalls like slow performance or broken XML.

Hi Jainam,

Can you break a translation file (one language) into multiple pieces?

How can you publish it later normally, or do I have to combine the translation somehow?

We developed an in-house extension to process translation files.
In simple terms, import the translation xlff file into bc, process it on bc ui, and finally export it.
Hope this gives you some tips.

Thanks
