What was the destination directory of your .xml file when you configured/created the .pcg file in package studio?  The default in package studio is usually %sdcard%\.   Any destination folder can be specified as long as MobiControl device agent has the permission to write to that folder.  Hence, the simple choice is public folder such as %sdcard%\Download\.  

Once the .xml file has been transferred to the specified destination folder,  it should be the post-install script that will be executed to copy/move the file to \Storage\IPSM\honeywell\persist\.   not pre-install script as you said in your post.  You also have to make sure the directory   \Storage\IPSM\honeywell\persist\ is writable by the device agent and the path is correct (e.g. path delimiter is \ rather than / on your device, etc.)

Hello Raymond.

I can not find where i can change dest point, so just find copied file in explorer - you are right - it was strored in sdcard folder.

Thanks - postinstall script worked well.

But my main problem was in using "\" 

this version works for me:

copy "%sdcard%/DataCollectionService.xml" "/storage/IPSM/honeywell/persist/"

Is the DataCollectionService.xml file already present on the device or are you placing it there with your Package? If you are placing it in sdcard yourself then the copy post-install script is arguably unnecessary as you could have just placed the file directly in the destination path.
