In closing, I'd like to share the sentiment passed on by several readers that this holiday season is a great time to register shareware (and a registered copy of one of the many excellent shareware games from Ambrosia, Stairways, and others could prove an excellent and inexpensive present that can be enjoyed during time off). Cheryl Linker <email@example.com> commented, "Register your loved ones' shareware for them. What a great way to double the gift giving!"
Extract Directly from Time Machine
Normally you use Time Machine to restore lost data in a file like this: within the Time Machine interface, you go back to the time the file was not yet messed up, and you restore it to replace the file you have now.
You can also elect to keep both, but the restored file takes the name and place of the current one. So, if you have made changes since the backup took place that you would like to keep, they are lost, or you have to mess around a bit to merge changes, rename files, and trash the unwanted one.
As an alternative, you can browse the Time Machine backup volume directly in the Finder like any normal disk, navigate through the chronological backup hierarchy, and find the file which contains the lost content.
Once you've found it, you can open it and the current version of the file side-by-side, and copy information from Time Machine's version of the file into the current one, without losing any content you put in it since the backup was made.
