Faster Drupal uploads with Parallel Plesk control panel

This may help others who are also using Parallel Plesk control panel (I'm using v11.5), to upload Drupal files faster. I am not using Shell access, but the standard Plesk control panel.

Slower method (about 40 mins)

1. Download Drupal 8 gzip file to a Windows directory
2. Un-gzipping the files
3. FTP the files to a directory on my server.

The 11,000+ files were taking about 40 minutes to upload via FTP. Deleting an old installation was also taking at least 20 minutes, because the FTP has to issue each delete command separately to the remote server.

Faster method (about 2 minutes)

1. Although gzip files are smaller than zip files, this method requires the latter.
2. Downloaded Drupal 8 zip file to a Windows directory
3. FTP the zip file to my Subscription root directory (not the server root). This directory contains all the directories for each of my Subscription's websites
4. In Plesk, in my Subscription's webspace, click the Files tab to view the File Manager
5. Locate the newly uploaded zip file (probably at the bottom of the page), and click the checkbox at the beginning of the line, to select it.
6. From the More drop-down, select Extract Files. A window pops up, noting that it "Extract files to the following directory: /". Confirm
7. The zip file contains a single directory that will be recreated in your Subscription's root. It takes only a minute or so.
8. Local the new directory, named after the version of Drupal you downloaded, eg. drupal-8.0.0-beta2
9. I couldn't find how to rename a directory in Plesk, so back to FTP, and rename the directory there, eg. to drupal8

And then when I configure a domain, I specify that it points to my new directory.
