Whatever you append to "nul." (mind the dot) it will be discarded. And
getting filelist from user "nul" indeed doesn't work. It throws a couple
of misleading messages in the transferview , the download fails and the
item doesn't disappear from the transferview at all.
Strange because we have a function to fix filenames to save (e.g. for hublists)
and IIRC the WIN32 part of that function checks for these reserved words. It
doesn't seem to be used in the filelist name formatting though.
Asterisks, ?, <>, etc.. in the nick probably cause the same problem.
There's two problems here. The error handling of the errors during any
the save of any filelist and the file name formatting itself to avoid
the reported error.

Title:
Filelist Download Failure From Specific Usernames
Status in DC++:
Confirmed
Bug description:
There is an issue with DC++ when a user chooses a nickname that
happens to be a Windows Reserved Keyword. For example, if a user
chooses a nickname from the following list:
CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8,
COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9 (Reference:
http://en.wikipedia.org/wiki/Filename#Reserved_characters_and_words)
a Windows user trying to download the filelist from a user with one of
these nicks will fail because the filename is in the format of
*nick*.xml.bz2 (ex. "aux.xml.bz2"), which is disallowed under Windows.
When DC++ attempts to write the remote user's filelist to disk, the
download will hang because Windows blocks the writing of this file to
disk. There is no error message displayed to the user during this
process and the reasons for the download to hang are not clearly
apparent. The person that is using this nick will have no issues,
because their filelist is named files.xml.bz2 which is allowed.
Ideally, the above list would be disallowed as a username so that
Windows users can download their filelists. Other clients would need
to adopt this blacklist as well to be good net citizens towards
Windows users.
