Local file name is too long and error creating a directory. Because of a limitation in Microsoft Windows which does not allow to create paths that are longer than 256 characters, you might get this notification when syncing data from our servers to your local Vault.
SecureBox adds an extension to the path/file when it is being synced down to your local Vault, for as long as the synchronisation is not complete. You can compare it with downloading a file from a website, Windows will then use your temp folder, we add an extension while the download is in progress. When the synchronisation is finished, we rename the file/path to its real name.
However, adding the extension can exceed the path length limitation in Windows and your computer will refuse to create the (temp) file, causing the synchronisation not to work properly. The only work around for this is to shorten the filename.
