vb.net - Visual Basic path asterisk -


i'm trying figure out how replace char (random) char in path example, don't need check multiple times (exemple : *:/program files/abc/*.cfg). in exemple, delete .cfg files in folder on every disk drives.

what i've tried : 

if my.computer.filesystem.fileexists(dir & "\abc\?\?.cfg")         my.computer.filesystem.deletefile(dir & "\abc\?\?.cfg") end if

i don't think it's possible use wildcard disk drive (at least couldn't find way it), can quite drives on computer , run loop, using driveinfo.getdrives method:

for each drive driveinfo in driveinfo.getdrives()     dim filepath string = string.format("{0}test1.txt", drive.name)     if file.exists(filepath)         console.writeline(convert.tostring("exists: ") & filepath)     end if next

update
in order use wildcards, must use directory.getdirectories , directory.getfiles instead of file.exists:

dim wildcardpath string = "abc\*" dim wildcardfilename string = "*.cfg" each drive driveinfo in driveinfo.getdrives()     try         dim dirs string() = directory.getdirectories(drive.name, wildcardpath)         each dir string in dirs             dim files string() = directory.getfiles(dir, wildcardfilename)             each filename string in files                 if file.exists(filename)                     console.writeline(filename)                 end if             next         next     catch ex exception         console.writeline(ex.message)     end try next

note: exceptions when attempting read dvd drive if no disk inside, , when attempting find directories doesn't exists (i.e if have z drive , no z:\abc directory exception "could not find part of path z:\abc").
