I don't think there is any meaningful limit. (2**31) - 1 I would guess. -----Original Message----- From: Kurt Buff [mailto:kurt.b...@gmail.com] Sent: Tuesday, February 12, 2013 4:02 PM To: NT System Admin Issues Subject: Re: file limitation error
Um, maybe... If you simply increment with a batchfile using ASCII names for the directories, such as: x:\a x:\b etc., through x:\12345678901234567890........ with no subdirectories, I wonder how long before you reach a limit. I haven't run across documentation regarding that.
