os: windows 7
build: 20.04.2001 morning (cant remember the build number)

so i created a new folder when i wanted to save a obj file from the filemanager and that created a strange thing (folder) that did not exist for windows but i could still see it and open it but not delete or write anything in it. (see attachment)

after several hours of search i found some help in an irc channel and they told me to try "dir /x" in the command prompt.this listed a folder~1 as name. so i could use "rd folder~1" to remove it.

not sure how this happened but it might be a good idea to check for bad symbols in folder names before creating them so such things do not happen.
