I have just restored a mailbox from an old backup, and some of the messages downloaded have names too long for our file system.
I have tried to rename them, but it comes back saying that that file name is not found.
(I am using ren command from DOS command prompt)
I have shortened the folder name that contains these messages to one character, there is nothing else I can shave off.
Isn't there a DOS command that forces to delete everything in the folder, such as del *.*?
(this also comes back that file name is too long.)
I think the key is to rename the files, but I have had no success.
Please advise.

There is a dos command called SUBST which allows you to assign a drive letter to some folder
eg
SUBST K: C:fooarsomelongpath

Now you can access further down the tree from K:

Do you try  this ?
del /F *.*

Or

del /F /S *.* (delete the directory's sub directory but take care of it )
