This is a follow on question to "[How do I delete 1 file from a revision in SVN?](https://stackoverflow.com/questions/33778/how-do-i-delete-1-file-from-a-revision-in-svn)" but because it probably has a very different answer and I believe that others would benefit from knowing the answer.

that the answer to the question "**How can I find the revision history of the file that was deleted and then resubmitted to SVN?**" is that you can't.
With a simple
```
svn log -v [folder]
```
you can browse quickly the adding and deletion.
```
