You'd have to have shared a folder on Toshiba and called the share "c". And have a folder on the 'c' share called 'mydir'.

>If I write \\\\toshiba\\c:\\mydir it doesn't...

No way will this work. The colon is an illegal character. You might try searching Google for "UNC examples".

>If I write \\\\toshiba\\c$\\mydir it doesn't...

Ditto. Won't work. C$ isn't a public share.

>If I write \\\\toshiba\\mydir it doesn't...

Is MyDir a legitimate share name on Toshiba?

>And if I write \\toshiba\...etc. it complains in the first place because of the single backslashes...

Right. There's no point in trying that.

>Please, show me an example with the correct syntax...(toshiba is the name of my computer).

Well, we have. Hopefully you're not pointed in the right direction to find your answer.
