--- Comment #6 from Thomas Baumgart <tbaumg...@kde.org> --- I tried this using Version 5.0.7-f8ae85c34 (the current is 5.0.8-029de4701 but that does not matter I guess) on a Windows 10 Professional 64 bit system. It can backup to a local drive (C:\users) and a network attached drive (SMB) without problems. The only problem is a leading '/' character in front of the drive code that appears when I select the directory using the 'Choose' button right to the mount point, but manually removing this superfluous character solved the issue. The 'Mount this directory before backing up' checkbox must not be marked on Windows. I thought we removed that already but apparently not. I am wondering what happens in case you execute the following command in a CMD shell window: cmd.exe /c copy /b /y xxx + nul E:\test.kmy where you replace xxx with the absolute path (use \ as dir separator) to your data file. Does it make a difference if KMyMoney is running or not. On the above mentioned system this copies the file without problems. Since you mention that it works on 4.8 I checked the code. 4.8 uses KIO::NetAccess::upload() to store the file, a functionality that is not available in KF5. That explains at least why it works on the older version. Are you really using Windows CE? -- You are receiving this mail because: You are watching all bug changes.
