The folder named "z:\original" has hundreds of sub-folders containing multiple copies of the same .jpg files. I wanted to copy all .jpg files into a folder named "z:\dump" WITHOUT the folder structure and hopefully overwrite most of the copies. I used
copy-Item -path "Z:\original" -filter "*.jpg" -Destination "Z:\dump" -recurse -verbose
but this recreated the structure with the .jpg files. How can I dump all files into a single folder, using PowerShell?
Use combination of dir/Get-ChildItem and Copy-Item with pipeline.
$_.FullName - Full path to jpg file
$_.Name is file name only
Get-ChildItem Z:\original\*.jpg -Recurse | %{Copy-Item $_.FullName "Z:\dump\$($_.Name)"}
You might need to add -Force to overwrite same files

I am trying to copy all the files in a directory that contains many subfolders into a single separate folder. When the code is run again, rather than replacing each file in the destination folder, it should skip files that have the same timestamp and only replace those that are older.
I have used robocopy to skip the copying of files that are of the current version/older in the destination folder. However, robocopy only copies the entire directory along with its folder structure so I am unable to obtain the desired folder with a list of all the files from the source.
I have also used get child-item and then copy-item. However, although this is able to get rid of the folder structure, it overwrites each file for each iteration and is thus time-consuming.
So what I want is to combine the capabilities of robocopy and copy-item. Note that there are no specific pattern to the files that I am to copy. It is simply to COPY each file in the subdirectories that are EITHER of a NEWER version or NON-existing into a single folder.
#For copying and ease of updating destination folder
robocopy /purge /np /S /xo 'source' 'destination'
#To copy items into the destination folder without keeping folder structure
Get-ChildItem -Path 'source' -Recurse -File | Copy-Item -Destination 'destination'
Was unable to combine both, So I am stuck with using the 'copy-item' code, which is quite time consuming when copying/updating large amounts of files.
The purpose of robocopy is to preserve the folder structure. If you want to mangle subfolders robocopy is not the right tool. Use the Get-ChildItem approach, group the results by file name, sort each group by date, pick the most recent file from each group, and copy it if the corresponding destination file either doesn't exist or is older.
Something like this should do what you want:
Get-ChildItem -Path 'C:\source' -Recurse -File |
Group-Object Name |
ForEach-Object {
$src = $_.Group | Sort-Object | Select-Object -Last 1
$dst = Join-Path 'C:\destination' $src.Name
if (-not (Test-Path $dst) -or ($src.LastWriteTime -gt (Get-Item $dst).LastWriteTime)) {
$src | Copy-Item -Destination $dst
}
}
I'm trying to copy all of the files with .py extension from one directory to a new one using PowerShell, but I don't want to recreate the directory structure. I want this to work recursively as the the py files are in numerous subfolders. In my destination directory, I want nothing but the py files.
Here's what I have now but it copies the directory structure too:
Get-ChildItem "C:\Johns Stuff\Python\" |
Copy -Destination C:\Users\dread\python -Recurse -filter *.py
How about:
Get-ChildItem "C:\Johns Stuff\Python" -File -Filter *.py -Recurse | ForEach-Object {
Copy-Item $_.FullName C:\Users\dread\python -WhatIf
}
The -File parameter (new in PowerShell 3.0 and later) will get only files and not directories.
Of course, remove -WhatIf to actually execute the command.
Copy-Item -Path D:\DB-DNLD\ -Filter *.csv -Destination D:\Dump\CSV -Recurse
I used this command, but it copied all .csv files along with existing folder structures, but my intention is just to copy all CSV to new single destination folder excluding source folder structures.
The Copy-Item cmdlet will maintain the tree structure. If you want to flatten the structure, you can locate the items with Get-ChildItem cmdlet then pipe that to a loop where each file it copied to the destinition folder individually.
dir -Path D:\DB-DNLD\ -Filter *.csv -Recurse | ForEach-Object { Copy-Item $_.FullName D:\Dump\CSV }
I have a PS script which Zips up the previous months logs and names the zip file FILENAME-YYYY-MM.zip
This works
What I now want to do is copy these zip files off to a network share but keeping some of the folder structure. I currently a folder structure similar to the following;
C:\Folder1\
C:\Folder1\Folder2\
C:\Folder1\Folder3\
C:\Folder1\Folder4\Folder5\
There are .zip files in every folder below c:\Folder1
What I want is for the script to copy files from c:\folder1 to \\networkshare but keeping the folder structure, so I should have 3 folders and another subfolder in folder4.
Currently I can only get it to copy the whole structure so I get c:\folder1\... in my \\networkshare
I keep running into issues such as the new folder structure doesn't exist, I can't use the -recurse switch within the Get-ChildItem command etc...
The script I have so far is;
#This returns the date and formats it for you set value after AddMonths to set archive date -1 = last month
$LastWriteMonth = (Get-Date).AddMonths(-3).ToString('MM')
#Set destination for Zip Files
$DestinationLoc = "\\networkshare\LogArchive\$env:computername"
#Source files
$SourceFiles = Get-ChildItem C:\Sourcefiles\*.zip -Recurse | where-object {$_.lastwritetime.month -le $LastWriteMonth}
Copy-Item $SourceFiles -Destination $DestinationLoc\ZipFiles\
Remove-Item $SourceFiles
Sometimes, you just can't (easily) use a "pure PowerShell" solution. This is one of those times, and that's OK.
Robocopy will mirror directory structures, including any empty directories, and select your files (likely faster than a filter with get-childitem will). You can copy anything older than 90 days (about 3 months) like this:
robocopy C:\SourceFiles "\\networkshare\LogArchive\$($env:computername)\ZipFiles" /E /IS /MINAGE:90 *.zip
You can specify an actual date with /MINAGE too, if you have to be that precise.
How about Copy-Item "C:\SourceFiles\" -dest $DestinationLoc\ZipFiles -container -recurse? I have tested this and have found that it copies the folder structure intact. If you only need *.zip files, you first get them, then for each you call Resolve-Path with -Relative flag set and then add the resultant path into Destination parameter.
$oldloc=get-location
Set-Location "C:\SourceFiles\" # required for relative
$SourceFiles = Get-ChildItem C:\Sourcefiles\*.zip -Recurse | where-object {$_.lastwritetime.month -le $LastWriteMonth}
$SourceFiles | % {
$p=Resolve-Path $_.fullname -relative
copy-item $_ -destination "$DestinationLoc\ZipFiles\$p"
}
set-location $oldloc # return back
I want to copy file
base.txt
To Other Folders And I want his name change To The Folder Name.
cd c:\Program\Levels
copy-item *.txt c:\Books -force -recurse
Get-ChildItem C:\Books -Filter *.txt -Recurse | Rename-Item -NewName { $_.Directory.Name}
So he's copying *.txt for the folder 'Books' and renaming the file to 'books.txt' but, he did not copy the file to subfolders within 'Books'
I want it to copy the .txt for subfolders in 'Books' and rename the .txt to the folder name.
Obs: the .txt file is unique
So the file base.txt which is presumably some sort of template will be copied to each subfolder in C:\Books? I think I can understand your logic approach but I offer this as a solution instead.
$templateFile = "C:\temp\base.txt"
Get-ChildItem "C:\Books" | Where-Object {$_.PSIsContainer} |ForEach-Object{
$newName = "{0}\{1}.txt" -f $_.FullName, $_.Name
Copy-Item -Path $templateFile -Destination $newName
}
Gather each subdirectory of "C:\Books" and in each of those directories copy the file base.txt to its new location where its name is the name of the parent folder.
