Am I doing something wrong?
It is really very hard to say without a detailed description of the steps you followed.
The normal procedure would be:
- In Finder navigate to the folder where you would expect the missing file(s) to have been located
- Select the folder (see note below)
- Enter Time Machine (I assume that is what you meant by "Time")
- Using the Time index in the right margin select a point in time when you know or suspect the files would exist
- In Time Machine scroll through the files in the folder — you can drill down through sub-folders as well — until you locate the desired file(s)
- Select the file(s) in Time Machine then click on Restore
- If the file does NOT exist in the folder as of the time you attempt the Restore the file will be placed in the original folder without further ado
- If the file DOES exist in today's copy of folder, Time Machine will offer three alternatives
- Keep the ORIGINAL file (ie. the file that currently exists in the target folder)
- Keep BOTH the current copy and the restored copy of the file(s) in the same folder
- REPLACE the file currently in the target folder with the file restored from the Time Machiine backup
- In my experience there is little or no delay in the operation and the only way you know it happened is Time Machine quits.
NOTE: If you enter Time Machine without previously selecting a folder in Finder it will default to the Desktop Folder.
The restored file will be in the original folder, and you should be able to locate it using Spotlight.
