Requirements: The server used several years down, found that our disk has a number of similar folders, we would like to merge this folder into a specified folder, and delete other unused folders.

Step 1, we open our server, D disk under the 5 years of Information Summary folder, some of the files are the same, some are different. such as:

650) this.width=650; "Width=" 864 "height=" 608 "title=" qq picture 20150212110724.png "style=" width:720px;height:472px; "alt= "Wkiol1tchpgc9le1aapnkxz4da4630.jpg" src= "Http://s3.51cto.com/wyfs02/M00/59/AE/wKioL1TcHpGC9le1AAPNKXz4da4630.jpg"/>

Step 2, search out the files of these 5 folders, and the previous year's folders and the latest "15 Information summary" to compare, such as the file name is not the same copy it to the "15 Information summary."

#不要遍历查找, subfolders copy directly $total 14=get-childitem "D:\ 14 Summary of information materials   | foreach {$_.name}  #不要遍历查找, subfolders copy directly $total 15=get-childitem "D:\ 15 Summary of information materials   | foreach {$_.name}  #不要遍历查找, subfolders copy directly

Get-childitem-recurse-path "d:\15 Annual Information Summary"-include "Copy file log. txt" | Clear-content
foreach ($a in $total 11)
{
if ($a 11-notin $total) #假如11年的文件夹里面的文件在15年文件夹里面均不存在, copied from 11 to 15
{Copy-item-path "d:\11 Annual Information summary \ $a"-recurse-destination d:\15 Year Information summary
Write-host "Find new documents in 11 information summary $a 11 and copy to 15 information summary"
$a 111 = "New file found in 11 information summary $a 11 and copied to 15 information summary"
$a 111| Out-file "D:\15 Annual Information summary \ Copy file log. txt"-append-encoding UTF8 #输出到日志, easy to compare
}
}

$total 15=get-childitem "d:\15 Annual Information Summary" | foreach {$_.name} #因为15年文件夹已更新, so you need to find it again
foreach ($a in $total 12)
{
if ($a 12-notin $total) #假如12年的文件夹里面的文件在15年文件夹里面均不存在, copied from 12 to

{Copy-item-path "d:\12 Annual Information summary \ $a"-recurse-destination d:\15 Annual Information summary
Write-host "Find new documents in 12 information summary $a 12 and copy to 15 information summary"
$a 222 = "New file found in 12 information summary $a 12 and copied to 15 information summary"
$a 222| Out-file "D:\15 Annual Information summary \ Copy file log. txt"-append-encoding UTF8 #输出到日志, easy to compare }
}

$total 15=get-childitem "d:\15 Annual Information Summary" | foreach {$_.name} #因为15年文件夹已更新, so you need to find it again
foreach ($a in $total 13)
{
if ($a 13-notin $total) #假如13年的文件夹里面的文件在15年文件夹里面均不存在, copied from 13 to

{Copy-item-path "d:\13 Annual Information summary \ $a"-recurse-destination d:\15 Year Information summary
Write-host "Find new documents in 13 information summary $a 13 and copy to 15 information summary"
$a 333 = "New file found in 13 information summary $a 13 and copied to 15 information summary"
$a 333| Out-file "D:\15 Annual Information summary \ Copy file log. txt"-append-encoding UTF8 #输出到日志, easy to compare

}
}

$total 15=get-childitem "d:\15 Annual Information Summary" | foreach {$_.name} #因为15年文件夹已更新, so you need to find it again
foreach ($a in $total 14)
{
if ($a 14-notin $total) #假如14年的文件夹里面的文件在15年文件夹里面均不存在, copied from 14 to

{Copy-item-path "d:\14 Annual Information summary \ $a"-recurse-destination d:\15 Annual Information Material summary
Write-host "Find new documents in 14 information summary $a 14 and copy to 15 information summary"
$a 444 = "New file found in 14 information summary $a 14 and copied to 15 information summary"
$a 444| Out-file "D:\15 Annual Information summary \ Copy file log. txt"-append-encoding UTF8 #输出到日志, easy to compare

}
}

Step 3, after the final effect is as follows:
