Updraft back up plugin for WordPress will create multiple folders for Uploads and Plugins in the backup when the content amount exceeds a certain limit, you end up with folders named like:

• uploads.zip
• uploads2.zip
• uploads3.zip
• uploads4.zip

Issue is that it is a pain to manually combine them as there can be overlap from one folder to another.

Here is how to combine them to one folder using the Termnial in macOS.

Add all zip archives into one folder, name it like uploads-all. Change directory to uploads-all.

cd ~/uploads-all

• uploads-all
  • uploads.zip
  • uploads2.zip
  • uploads3.zip
  • uploads4.zip

Extract all uploads and merge them into a folder, example below is named uploads-combined, run:

for z in *.zip; do
  unzip -o "$z" -d uploads-combined
done

Now in the folder uploads-combined is an uploads folder which contains all the upload files merged. Which you can either move into your WordPress restore or zip to one archive.

zip -rX uploads.zip uploads/

That’s it, the same can be done for other multiple folders such as plugins.
