DenisChenu 2021-11-12 09:57 developer ~67267	Can you check and see what must be really fixed ? I must test a file with "\" uploaded via linux on a linux server but try to download via windows.

DenisChenu 2021-11-15 15:55 developer ~67331	I must test a file with "\" uploaded via linux on a linux server but try to download via windows. Seems $_FILES['uploadfile']['name'] remove the \ here … send `Check\..\..\brokewindows.txt` : get brokewindows.txt without any other fix on filamne (maybe some JS ?)
