Overview We sent a customer (MB - Lara Palmer) a link to download a 28GB file (DigiBeta). The customer was on a Mac and fiber (in Tofino). Took 3.5 hours to download. When it finished downloading it failed with an unzip error from the Mac. This is sending a download link from the Synology NAS.
When we send a link to a folder, the customer connects on the Internet and sees the files in the folder. The customer can select one file at a time to download or the entire folder to download ("Folder" button). If the folder is selected, then a zip of the folder is downloaded.
Instead of using the standard unzip program on a Mac people have found that using "StuffIt Expander" or "BetterZip" works. Our customer tried StuffIt and it worked fine.
I've submitted a trouble log to Synology and they are looking into it.
