AutoHotkey Community

Hello
I try to copy files to an other path as a backup
The resulting path is longer than 260 characters. So filecopy failes.
Is there any workaround to copy the files?
Thanks for the help

Try the native copy command?
Or perhaps xxcopy.
Shouldn't the path be in Unicode to go beyond the 255 char limits (up to 32,000 chars, IIRC)?

Hello PhilHo

xxcopy cant read from shadow devices
robocopy cant read from shadow devices but can write very long paths
copy like filecopy (autohotkey) can read from shadow devices, but cant write very long paths
so each of them has one fault.

As far as I see the paths do not need to be in unicode
I renamed a directory to contain more than 260 charakters and its OK

But in an other page I found:
"When using very long path names, prefix the path with the characters \\?\ and use the Unicode versions of the C Runtime functions."
What does unicode mean for the paths?

What do you call "shadow devices"?
You wrote: "I renamed a directory to contain more than 260 charakters and its OK" and "What does unicode mean for the paths?"
Internally, Windows maintains Unicode versions of the files and folders (using several Dos dir slots), along with the short name. IIRC, it does that even in Win9x.
If your names use only low Ascii (codes between 32 and 126), or probably even Ansi (codes above 127, in the default code page), Unicode paths probably means only that they are stored by alternating the Ansi codes and zeroes. There are WinAPI functions to do the conversion between multibyte chars and Unicode (WideCharToMultiByte and reverse).
Perhaps you should look the SHxxx functions (shell functions).

Hello PhiLho
Thnaks for the xplanation about unicode paths.
Shadow devices are a windows internal "devices" to access open files or keep snapshots. they can be accessed by the following synthax
\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1
YOu can create these snapshots on XP and on 2003
but its more easly implemented in Server 2003, because there these devices can be mounted as volumes. IN XP they are only temporarily created

Its very useful but on XP not easy to use
