The problem
Two notes can both be called final while differing in a date or instruction. A small text change can matter to the entire delivery.
A practical answer
GJ File Manager presents supported text differences in a shared view. Identify the left and right files first, then read changes rather than expecting an automatic merge.
Step by step
- Give the two sample text files distinct names in an accessible location.
- Select both and use your Compare shortcut, normally ⌥⌘D.
- Check the names and paths on both sides, then examine the changed project description or other lines.
- Make the decision in your editing application, save and compare again to confirm the intended changes.

Know the limits
This workflow is for readable text. Binary documents, scanned images and complex Office files should not all be interpreted as plain-text differences.
Common question
Will comparison choose the correct version?
No. It reveals differences; the source and task requirements determine what to keep or merge.
