TortoiseSVN (version 1.6.8 at the time of writing) has a HUGE documentation gap about exporting a versioned folder from the CLI (command line interface). If you type

TortoiseProc.exe /command:export /path:sourceFolder /closeonend:4

a dialog box will pop up requiring you to select the destination folder to export to, frustrating most efforts to write a TortoiseSVN batch script. Most forums recommend to solve this issue by installing and using Apache Subversion itself, a command line only application. But chances are that

• you do not want to install / use yet another application
• you cannot install / use yet another application
• you have to use TortoiseSVN anyway in your script
• exporting a working copy to a different location is done without using the Subversion library, so there's no matching command line equivalent
• etc.

What is NOT documented to export a versioned folder using TortoiseSVN, is a command line like this:

TortoiseProc.exe /command:dropexport /path:sourcePath /droptarget:destinationPath /closeonend:4

The /closeonend parameter is always optional. If you want to investigate further, we suggest you to have a look at the source file "ContextMenu.cpp".

If you found this tip useful, please contribute to the TortoiseSVN community to document this feature. Anyway, enjoy it.
