xcopy – a great tool

So, tired of copy and paste between folders/drives, and all of a sudden access is denied on a particular file so the transfer stops.. that sucks!

xcopy is a great tool on command prompt.

go to the directory you want to copy to and type:

xcopy {copy path} /C /H /K /R /E /Y

also note that if any of your paths have spaces in them, you need to enclose them with quotes, ie. xcopy c:\"documents and settings\administrator" /SWITCHES.
This does:
/C Continues copying even if errors occur.
/H Copies hidden and system files also.
/K Copies attributes. Normal Xcopy will reset read-only attributes.
/E Copies directories and subdirectories, including empty ones. Same as /S /E. May be used to modify /T.
/R Overwrites read-only files.
/Y Suppresses prompting to confirm that you want to overwrite an existing destination file. May be preset in the COPYCMD environment variable

Xcopy provides an excellent tool for backing up selected folders. With appropriate switches, a variety of backup scenarios can be created. One possible backup configuration would be to copy only those files that have been changed. Here is an example command:
xcopy C:\somefolder E:\backupfolder /D /E /C /R /H /I /K /Y
This command will copy all files, including those in sub-folders, that are newer in the source folder. It will copy hidden as well as read-only files and will create the destination folder and/or sub-folders if they do not already exist.
