I need to copy all *.doc
files (but not folders whose names match *.doc
) from a network folder \\server\source
(including files in all nested folders) to a local folder C:\destination
without preserving the nested folders hierarchy (i.e. all files should go directly into C:\destination
and no nested folders should be created in C:\destination
). In case there are several files with the same name from different subfolders of \\server\source
, only the first one should be copied and never overwritten then — all conflicting files found later should be skipped (there could be many cases like this, and the skipped files should not be trasferred over the network, otherwise it would take too much time). Here is my attempt to implement it in PowerShell:
cp \\server\source\* -Recurse -Include *.doc -Container:$false -Destination C:\destination
There are at least two problems with this command:
*.doc
too.Can you suggest how to fix these problems?
Implementations using copy
, xcopy
, robocopy
, cscript
or *.bat
, *.cmd
are also welcome.
The local OS is Windows 8 and the file system is NTFS.
If you are copying files using drag-drop or copy/paste, you may simply choose “Skip this file” or “Skip these files” option to not overwrite the files that are already existed at the destination folder. Or, if you are using command line copy, you can answer N to bypass these files that are already existed.
It's the /T option that copies just the folder structure not the files. You can also use the /E option to include empty folders in the copy (by default empty folders will not be copied).
By default when you run the PowerShell Copy-Item cmdlet, it will overwrite the file if it is already exists.
I would produce the list of files first and validate as you go through the list.
Something like this:
$srcdir = "\\server\source\";
$destdir = "C:\destination\";
$files = (Get-ChildItem $SrcDir -recurse -filter *.doc | where-object {-not ($_.PSIsContainer)});
$files|foreach($_){
if (!([system.io.file]::Exists($destdir+$_.name))){
cp $_.Fullname ($destdir+$_.name)
};
}
So, use Get-ChildItem
to list files in source folder matching the filter, pipe through where-object
to strip directories out.
Then go through each file in a foreach
loop and check if the filename (not Fullname) exists in the destination using the Exists
method of the system.io.file
.NET class.
If it doesn't, copy, using only original filename (dropping original path).
Use the -whatif
option on the copy when testing, so it only displays what it would do, in case result is not what you wanted :-)
