A question about Auto Save, Versions and Preview.

Do I understand right that it is not possible to turn off Lion's Auto Save?

Correct. But in most cases, that's not a problem.

And that the autosavings are stored in a hidden sqlLite data base?

Some are; when either you or Autosave makes a new "version," the deleted/changed portions are put there. The actual file always contains the current version.

Is Lion's Auto Save going to save every file I take a look at in Preview?

No. It won't do anything at all, unless you edit the document.

At the moment, Autosave and Versions apply only to TextEdit, Preview, and the recent updated Numbers and Pages.

That's a bit misleading; it won't make duplicate copies of anything unless you make changes. Note that everywhere else, it talks about "as you work" and "as you make changes."

It's all geared to editing documents, not just viewing them.

I'll see if I can get that line changed, though, but don't hold your breath. 😉

EDIT: I think it means, "Each time you open a new document . . . "

Every change you do in a document it save it in the current document and create a version for the documents before the change,i think you shall want to loss some change or document to loss it because it no only saving like you doing before with save or save as it also is keeping record of all your changes so is like if everytime you do a change you make a copy before and after the change.I think is more a pro than a con to upgrade ..

As noted in the first and third posts, he's not changing anything; but was concerned that merely viewing a document would make a duplicate copy.

The amount of disk space it uses and where (on which disk) is a bit of a concern to me.

When you edit a document, the changed "chunk" is put in a hidden folder on the same drive as the file. So the amout of space taken should be relatively small.

And, they're periodically "thinned," keeping "hourly versions for a day, daily versions for a month, and weekly versions for all previous months."

I have problems with Preview altering photos, I used to use it for a quick way to resize images for emailing or putting on Flickr. Now it doesn't allow me to "save as" I have to remember to duplicate the image before resizing otherwise I seem to lose the original. I still have the RAW file so all is not lost. Sometimes it was easier to just to use Preview than open in Photoshop.

The rest of Lion is good but I wish preview would go back to what it was before.

I don't know how this has progressed, but Autosave is a nightmare. I figured it out when I opened a photo in Preview, resized it, decided resolution was too low, and clicked the red button. To my horror there was no "do you want to save?", it had already saved my (useless) 72 dpi file. I had to dig out a backup, which was time I didn't need to waste.

Please, Apple, let us turn off Autosave.

I actually think Preview has a bug. When you copy and "New from Clipboard" then "Save...." as JPEG or PNG or any image file - you can't resize - the resize is dimmed. When you close the image and re-open it you can resize. No wonder peopel can't get onboard with the new concept - looks like the code developers didn't even get it either............
