Compress Files

Requirements

Install the open source software 7Zip, which has a nice interface for this. After it's installed, log out an back in.

In Explorer, select multiple items. Right click and in the context menu go to

7-Zip -> Add to "foldername.zip"

Think of a checksum as a certificate of authenticity for your file. It ensures that the file has not been altered or corrupted during transfer.

Next, right click the new zip file and go to

7-Zip -> CRC SHA -> SHA-256 - foldername.zip.sha256

Go back to the [[index#Omeka Tutorials|Homepage]] to finish the steps

I don't have a Mac, but everything should work the same. I'll be borrowing a Mac soon to test this out.
