# What is the difference between a 'replace' and 'append' Dataprep integration?

Replacing a file means changing the single input file that was initially used for integration. Append file, on the other hand, means attaching another file having the same format to the existing file(s) integrated in the platform.

When a Dataprep job is run, these files are merged and processed through the Dataprep recipes. All these files are listed and the user can download these input files and also delete an appended input file if needed from the Data Upload tool directly.
