Hey man, awesome vid. Is it safe to put up to 4 GB of files in this? Would they corrupt? Thats the last thing I want it to happen.

And is it wise to keep on opening it and closing it every day?

I only have 3 encrypted disk images on my system and the largest of those is around 200 MB. I can't speak to the integrity of the virtual file system employed in a disk image because I only open my encrypted disks once a month at the most. From my experience, HFS+ is a pretty robust file system and I've never encountered any file corruption in 5 years of daily use. If you're paranoid about corruption occuring, then I would copy the files, create a new image, and re-encrypt just to be safe.

How do you compact the Sparse file after you delete files? I deleted a bunch of files and there is no free space left. The file expands automatically but does no compress automatically. Thanks!

Despite the shaky camera, it's a great video; thanks!

On some OSX, there's no option to choose the disk size.

It keeps saying: source in use. What do I do wrong?

Thanks for doing this. I was looking for a simple way to encrypt specific important files without using File Vault (so that I could also use Time Machine for backing up everything else). Great video with very clear instructions.
