Maybe I misunderstand WINRAR. I have tried to compress a large file for sending. But after the compression the file is the same size. I did not split it into smaller files. Is that necessary?

I selected a file/Add/Selected an archive name/Selected RAR/ and chose NORMAL compression.

When the file was compressed it was the same size as the original.

Thanks for any ideas.

Some files can't be compressed further...

try 7Z.... works with a large variety of formats.

Thanks for the info. I will experiment with it. and post

If it's a highly compressed audio or video file you'll likely not get any compression out of it because these are already compressed. In fact, you might even end up with a bigger file.

I guess that it was an already highly compressed file, because I have been unable to compress it any further. Like LNCPapa said, sometimes I actually came out with larger files.

I did try 7Z but still no compression.

Thanks for everyones help. I understand these compression programs better now.

The file may not be capable of further compression.
