The problem with doing an svn merge as suggested by Sean Bright is that is reintroduces other changes made in the same revision as the deletion. An svn copy is a more targeted operation that will only affect the deleted files.
Using Tortoise SVN you can resurrect a file that has been deleted from your working copy directory and from later SVN revisions, via a svn copy as follows:
- Browse to the working copy folder that previously contained the file.
- Right click on the folder in Explorer, go to TortoiseSVN -> Show log.
- Right click on the revision number just prior to the revision that deleted the file and select “Browse repository”.
- Right click on the deleted file and select “Copy to working copy…” and save.
The deleted file will now be in the working copy folder. To re-add it back to SVN, right click on the restored file and select SVN Commit.
NB: This method will preserve the previous history of the restored file, however to see the prior history in the TortoiseSVN log you need to make sure “Stop on copy/rename” is unchecked in the Log messages dialog.
