This tickled me..so I (along several 1000 other network users) get an email saying I've got too much storage in my personal network drive (H:) which includes MyDocs, Downloads etc.
The IT support bods made a intranet page about this but instead of putting the advice of what/how to delete on there, they made a Word doc about it, with loads of uncompressed screen grabs so it totals nearly a 1mb file...and guess where it saves to when you open it....yup, the very place they are trying to reduce in size.
Nice one IT support bods.
