TortoiseSVN includes a spell checker which allows you to check your commit log messages. This is especially useful if the project language is not your native language. The spell checker uses the same dictionary files as OpenOffice and Mozilla .

The installer automatically adds the US and UK English dictionaries. If you want other languages, the easiest option is simply to install one of TortoiseSVN's language packs. This will install the appropriate dictionary files as well as the TortoiseSVN local user interface. After the installation finishes, the dictionary will be available too.

Or you can install the dictionaries yourself. If you have OpenOffice or Mozilla installed, you can copy those dictionaries, which are located in the installation folders for those applications. Otherwise, you need to download the required dictionary files from http://wiki.services.openoffice.org/wiki/Dictionaries .

Once you have got the dictionary files, you probably need to rename them so that the filenames only have the locale chars in it. Example:

Then just copy them to the bin sub-folder of the TortoiseSVN installation folder. Normally this will be C:\Program Files\TortoiseSVN\bin. If you don't want to litter the bin sub-folder, you can instead place your spell checker files in C:\Program Files\TortoiseSVN\Languages. If that folder isn't there, you have to create it first. The next time you start TortoiseSVN, the spell checker will be available.

If you install multiple dictionaries, TortoiseSVN uses these rules to select which one to use.
