Previously, I used the svn repo-browser to find the desired directory, directly selected the directory, and used the svn right-click checkout function to checkout the developed directory to the local disk.
However, after using the Vista system recently, it is found that this function is unavailable. When the checkout window appears, the "OK" button is always dimmed, it is assumed that the checkout function is not supported in Vista, and only one version can be exported using export.
Later, we found that right-click any blank space and select "checkout" from the right-click menu. In the pop-up checkout window, previously, the "OK" button, which was always dimmed, was miraculously black and can be used. However, it is quite awkward because it is inconsistent with the previous usage habits, at least the file can be synchronized with the server.
The Client Version of tortoisesvn I use is 1.5.5.
