Is there a workaround for files with unsupported characters that don't sync?

Hi

I'm aware that there are restriction on windows filepath characters that drop box does allow.

I have access to a dropbox which I want to download using the desktop app so that the file modified date is preserved (Doesnt seem to be on the website downloads).

Unfortunately a couple of the folders names in the dropbox have colons in so those folders don't download.

Is there any work around to this (e.g. an option to substitute characters in the download paths that windows encounters and doesnt like) or some other way to download the individual files (which dont have colons in their name) and preserve the modified date.

I dont have any access/permissions to change the folder names in dropbox itself

Many thanks
