We took a 60mb Wav file and compressed it using Winrar. The end result was a file size that went from 60mb to a mere 6.8mb. This compression was so good we decided to add it as an upload option. This is a perfect solution for those that have huge files and need it under our 60mb upload limit
Obviously, you will need the Winrar program to compress your files but there is a trial software that can be downloaded I personally have been on a trial version for years now.
Once your files have been compressed, you can then upload your .rar file in the control panel
The great thing is that Winzip that is pretty much used everywhere can unzip .rar files so your customers don't need to have Winrar.
