Theme Update

Topic summary

Main issue: A merchant needs an easy way to find which Shopify theme files contain custom code before performing a theme update.

Key update: There is no built-in Shopify feature that identifies or tracks edited theme files.

Suggested approach: Use the third-party “Diffy” app from the Shopify App Store. It supports theme backups and file versioning (tracking changes across versions and comparing differences), which can help locate modified files before updating.

Outcomes/decisions: No native solution offered; one external tool recommended.

Status: Unresolved/ongoing. The original poster did not confirm whether the suggested app met their needs, and no alternative methods were provided.

Anyone know an easy way to identify which theme files you added custom code to. I have a theme update but cant remember all the files I made changes to.
