Help us translate TreeSize Free

We are proud of the popularity of our award-winning disk space management software Treesize and would love to offer it to everyone in her/his native language. In this way, all our worldwide users can enjoy localized TreeSize software with ease.

Badge users love us

TreeSize is already available in German and English. Thanks to the help of our great volunteer translators we are looking forward to translations into French, Spanish, Portuguese, Chinese and Japanese, which will be released with the coming version. But we want more! Our TreeSize should be able to speak any language in the world. Do you want to help us achieve our goal?
