Tilde (~) added to file name?

The other day, iBooks Author began creating duplicate files on save with a tilde (~) character at the end of file name. Anyone know what's going on here and how to make it stop?


I'm wondering if it has anything to do with Lion 10.7.3, which I updated to the other day, right around the same time this started happening.

I don't think that's it. The file is the same size and opens when I double-click it. And it doesn't go away when I quit iBooks Author. None of that is consistent with a versions file that only contains changes. It's as if iBooks Author suddenly thinks it needs to make a copy of every file.


Now I'm starting to wonder whether this is Mac OS 10.7.3 related. But it doesn't do it with other apps that support versions, so I don't know.

Is this is a "temporary" file, then why isn't it going away when I close the document and quit iBooks Author?


Although I agree that it's named like a temporary file, it must be a pretty serious bug in 10.7.3 if temporary files aren't deleted when the app quits. This particular file is 64MB; I can image eating up a hard disk with multiple versions of the same file just sitting around when they're no longer needed.


And this doesn't explain why I don't experience the same problem in an app like Pages, which also supports autosave and versions.


I hope you're right and, if it's a bug in Mac OS, it's fixed promptly! While I can manually remove these duplicates on my hard drive, I'd hate to fill my Time Machine backup with a lot of files I don't need.

You will lose the context as represented for that book, at that point in time. It is 'safe' to delete them in the sense that it won't hamper your editing ability in whatever other versions you are still maintaining.


Are you adept at navigating versions from an app in Lion? If not, look at the top of a book's main window, and click where it says 'Edited' to see options.

What you said is - by deleting the one with ~, "You will lose the context as represented for that book, at that point in time. It is 'safe' to delete them in the sense that it won't hamper your editing ability in whatever other versions you are still maintaining."


If the one without the ~ is the current version, by deleting the one with ~, you should NOT lose the context as represented for that book at that point in time. You will only have the book a that point of time. What you lose is OTHER version. So it is the reverse.

See Lion's Help on: versions


KT you are correct.


To see this in action place the file you are working on you desktop. Then make a few changes in iBooks Author and see the 'phantom file' appear too on your desktop.


Save a version of all your work and see the tilded version disapear since it is no longer needed.


Neat! and it is defintely a feature of LION.


I read through some more posts and noted you updated to include correctly this appears with other Apple files on Mac. I work with all kinds of documents on the desktop and then clean up after the day is done by moving them elsewhere. TexEdit and other programs, even Preview at times produces this tilde version for a few minutes. It is data not commited yet.
