From the context menu for that folder, click on
TortoiseSVN →
Apply Patch... This will bring up a file open dialog allowing you to select the patch file to apply. By default only
.patch or
.diff files are shown, but you can opt for “All files”. If you previously saved a patch to the clipboard, you can use
Open from clipboard... in the file open dialog. Note that this option only appears if you saved the patch to the clipboard using
TortoiseSVN →
Create Patch.... Copying a patch to the clipboard from another app will not make the button appear.
Alternatively, if the patch file has a .patch or .diff extension, you can right click on it directly and select
TortoiseSVN →
Apply Patch.... In this case you will be prompted to enter a working copy location.
