Hello,
I tried to compress a file (slideshow with text and music) of 19.6 MB using the "archive" function on MAC. It worked well, but the output is 19.3 MB. Weak compression! Is it possible to achieve stronger compression, how? I have Stuffit Expander, but I can only decompress. I don't have the "compress" function.

Hello,
Try 7zX, which is free to my knowledge (http://ww11.xmghosting.com/ It compresses a .pps of 3.3 MB to a .7z of 2.5 MB, which is a 25% reduction. The downside: I believe your potential correspondents also need to have it to unpack the file (there's a self-extracting format; often, that hinders compression).
Stuffit may be more efficient, but it is probably paid.
Sincerely

Hello,
The zip archives do indeed compress very little, and it also depends on the type of files.
You need the full version of Stuffit, not Expander which is free but only decompresses.

unless you search on Versiontracker for Mac OS to find freeware
Best regards

Hi, you can compress from the command line with gzip filename
which creates a filename.gz that is quite effective, standard, and free.
To do this in a Terminal window on OS X.
I would be surprised if the Windows world couldn't read/decompress .gz files
That said, the compression rate depends on your file.
Image + sound... it's already very compressed?

Thank you for your answers, unknown friends. I tried compressing with zip and gzip. Each time I go from 16.9 to 16.3 MB. That's not much. It's a .mov file. Is that the reason?
Best regards.

Hello,
I just found a really simple solution to reduce the size of a slideshow on Mac OS 10.4. Go to file, export. Three format sizes are offered: large (640x480), medium (320x240), small (240x180). Starting with a file of 21MB, I went down to 19.7MB, 7.6MB, and 4.7MB for each size. In the end, you can enlarge the viewing window. Of course, you lose image quality, but it's still readable, and in any case, I was able to send my slideshow as an attachment with my internet subscription limited to 5MB. I don't know yet what it turned out like when received on PC.
Question that's unrelated: I'm using Tiger, is it worth upgrading to Leopard?

Yes, Leopard is a big (r)evolution of MacOSX:

Leopard is young and has some bugs:

But here's what might hold you back from switching to Leopard: are the Apple and other applications you use compatible or not with Leopard? Check the websites to see if updates have been released or are planned.
