Encryption

Protect (encrypt) other files using 7-Zip

7-Zip is the preferred file archive software at UWE Bristol. You can use 7-Zip to protect (encrypt) files that are not Microsoft (e.g. Word, Excel PowerPoint, these have inbuilt tools).

Steps

1.   To create the file, right click on the files or folders that you would like to encrypt, and select "7-Zip" > "Add to archive…"
