Combine files
To combine files, specify a single file for the destination, but multiple files as the source. To 
specify more than one file use wildcards or list the files with a + in between each 
(file1+file2+file3) 
When copying multiple files in this way the first file must exist or else the copy will fail, a 
workaround for this is COPY null + file1 + file2 dest1 
COPY will accept UNC pathnames 
Copy from the console
(accept user input) 
COPY CON filename.txt 
Then type the input text followed by ^Z (Control key & Z) 
To do this in Powershell use the following function: 
function copycon { 
[system.console]::in.readtoend() 

Examples:
In the current folder 
COPY oldfile.doc newfile.doc
Copy from a different folder/directory:
COPY "C:\my work\some file.doc" "D:\New docs\newfile.doc"
Specify the source only, with a wildcard will copy all the files into the current directory: 
COPY "C:\my work\*.doc"
Specify the source with a wildcard and the destination as a single file, this is generally only 
useful with plain text files.
COPY "C:\my work\*.txt" "D:\New docs\combined.txt" 
Quiet copy (no feedback on screen) 
COPY oldfile.doc newfile.doc >nul


COPY is an 
internal
 command.

CSCcmd - Client-side Caching command
 
Run this utility on a client PC to configure offline files. Offline files (CSC) allow the client PC to 
access copies of network files while disconnected from the network/domain. Files can be 
synchronized with the network when connected. 
Syntax 
CSCCMD Option(s
Options: 
/ENABLE Enable Client-Side Caching (CSC) on this client.
Requires Local Administrator rights 
/DISABLE Disable CSC, ensure all offline files are closed first. 
/Enum[: \\Server\Share [\Path]] [/RECURSE]
Display all the shares in the local cache. 
With the /RECURSE option, this will display the contents 
of the shares within a parent share. 
/DISCONNECT:\\Server 
/DISCONNECT:\\Server\Share
Disconnect a server or share from CSC on this client.
/MOVESHARE:\\Server1\Share \\Server2\Share
Move files and folders from one share to another in the 
cache. 
This is useful if the local cache must point to a 
new/renamed server location. 
/RESID Restamp all the entries in the Windows offline files 
(CSC) database 
with a new user security identifier (SID). 
useful when moving user accounts from an NT 4.0 domain to 
2003. 
/ISENABLED Is CSC is enabled on this client PC. (synonym: 
/ISCSCENABLED)
/PIN2:\\server\share\path [/USER] [/SYSTEM] [/USERINHERIT] 
[/SYSTEMINHERIT] 
Pin shared resources: 
Use the PIN2: /USER option to pin a file. This has the 
same result 
as using the Offline Files dialog box to cache the file. 
Use PIN2: /SYSTEM to specify that the share will be 
pinned via Group Policy. 


/USERINHERIT and /SYSTEMINHERIT] will determine how the 
pin data is inherited. 
/PIN2:filename /FILELIST [/UNICODE] [/USER] [/SYSTEM] [/USERINHERIT] 
[/SYSTEMINHERIT]
Use a file to describe the objects to pin 
The file contains the UNC path of each object to pin. 
/FILELIST = the objects are separated by a carriage 
return/linefeed. 
/UNPIN2:\\server\share\path [/USER] [/SYSTEM] [/USERINHERIT] 
[/SYSTEMINHERIT] [/RECURSE]
UnPin a shared resource or remove a shared resource from 
the local cache. 
with /RECURSE, CSCCMD will unpin all children of the 
path. 
with /RECURSE2, CSCCMD will unpin the path and children 
of the path. 
/UNPIN2:filename /FILELIST [/UNICODE] [/USER] [/SYSTEM] 
[/USERINHERIT] [/SYSTEMINHERIT] 
UnPin specific shared resources listed in filename.
/FILELIST = the objects are separated by a carriage 
return/linefeed. 
/FILL:\\Server\Share\Path
Copy server-side data to the local cache. 
/FILL:FileName /FILELIST [/UNICODE]
Copy server-side data to the local cache using a file. 
/DELETE:\\Server\Share\Path [/RECURSE] [/RECURSE2]
Delete a file, a directory, or a share from the local 
cache. 
Ensure that the directory/share is empty before you use 
this switch. 
with /RECURSE, CSCCMD tool only operates on the children 
of the path. 
with /RECURSE2, CSCCMD operates on the path and children 
of the path. 
/ISSERVEROFFLINE:\\Server
Does CSC consider \\server to be offline. 
To get a reliable response from this switch, you must 
first open a 
share/file/directory from the local cache for \\server 
/SETSPACE:Bytes
Specify the disk space in bytes to allocate to temporary 
offline files. 
These files are nonpinned, auto-cached files. 


This is similar to the function provided in the Offline 
Files dialog box. 
/CHECKDB [/QUICK]
Examine the CSC database and display any database error 
flags. 
/QUICK will skip the enumeration and just display 
database errors. 
/EXTRACT[:\\Server\Share[\Path]] /TARGET:Path [/RECURSE] 
[/ONLYMODIFIED] [/STOPONERROR] 
Extract a file, a directory, or a directory tree from the 
local cache.
This requires Local Administrator permissions 
/TARGET will specify a destination.(which need not 
already exist) 
/ONLYMODIFIED, extract only files that have been modified 
offline. 
/STOPONERROR, stop the extract if an error occurs. 
Offline files are most often used with laptops to provide access to data when on the move. 
Folder redirection can be setup to place the users 
My Documents 
on a server share, and then 
Offline Files can be set to copy and cache the data to the laptops C: drive.
This arrangement allows faster synchronisation of files than a full roaming profile (which also 
synchronises other things you probably don’t need on a laptop.) 
The /PIN2 switch does not copy the content of the shared resource into the local cache. Pinning 
is not sufficient to make the files available offline. After you use the /PIN2 switch, you must run 
CSCCMD /FILL to copy the content of the shared resource to the local cache. 
When using FILELIST, any white space at the start of a file is ignored. 
With the /UNICODE option, CSCCMD will create or read a file list in Unicode text format. 
CSC is available for Windows 2000/XP/2003.
