# Create a ZIP File

> How to compress files into a ZIP archive before uploading.

For uploads of more than 200 files, DekkoSecure strongly recommends compressing your data in to a ZIP file before adding it to the system. Uploading, sharing and downloading hundreds of individual files can take a long time because each one is uniquely encrypted on your computer.

**Note:** ZIP files cannot be unzipped in the DekkoSecure app.
