copying hidden files

[sted]

i have found a silly bit of software that stores some of it files in %userprofile%\local settings\temp (and then when you log in later on a machine the project fails to load)

 

the first lot of folders it creates are all called _name_of_project and have the hidden attribute set.

 

im trying to write a script to grab them at logout (or just running manually atm to test) but i just cant seem to get them to copy using _* as a wildcard it either copies nowt or all the otehr stuff in temp i dont want (dir * /ah works fine but xcopy y:\_* c:\trash /h /e returns 0 files copied but copies most of the temp dir (which ideally i dont want)

 

any ideas?
