Trying to upload a large downloadable file for a Virtual Product

[Lunar]

I have products that are virtual products and gives the user downloadable goods.

Because these files are large and can reach 600 MB, I am doing this:

1. I want to upload a 500 MB file called "myFile.zip"
2. I take a small JPEG image and rename it like "myFile.zip".
3. I upload it to the server using the Virtual Product section and save.
4. I go to downloads using FTP and take the name that was created, for example, "ccb3344377ef9cc69ae876357623c6a87a695b11"
5. I rename "myFile.zip" to "cca7cbb377ef9cc69ae254657097c6a87a695b11" and upload it to the server.

 

Now I try to download the file. The download happens ok, but when I try to unzip the file I get this error message: "Unable to expand myFile.zip - Error 2 - No Such File or Directory". I am on macOS High Sierra. The store is Prestashop 1.6.1.18.

What am I missing?

Did you compare the downloaded file with the original? Are they the same size? And are the also the same when you compare them with some tool?
