# What does Merge do in Data Parking?

Merge blends the source into a matching folder at the destination: it adds what's missing and keeps what's already there. It never overwrites a different file — a same-named file with different contents is renamed with the date and kept, and the source's version takes the name. Identical files are left alone. Once the copy is checked, the original is removed from the source side.

For example, a *report.pdf* already on the drive becomes *report (drive copy 27 Oct 2026).pdf*, and yours arrives beside it as *report.pdf*.

Because Merge never removes anything at the destination, it doesn't need a confirmation step. Use it when you're consolidating the same folder across two places — for example adding this month's exports to an archive folder on the drive.

If you'd rather the destination ended up an exact copy of the source, use Move instead. See [the three options compared](https://storagestudio.us/faq/moving-folders/what-is-the-difference-between-move-merge-and-relocate).
