With BizTalk, we often archive files in a sub directory. Personally, I would rather archive to a SQL database with a database column, but that takes a little more architecture and sales. So in the meantime, many clients continue to write files to disk. There are frequently clean-up jobs that delete files over x days old.

However, when there are multiple thousands of a files in any directory, it can take a long time to open that directory, and display the files, especially when you are accessing it from a remote computer.

The $DaysBack parameter can be set to non-zero if you want to only group files over x days old into sub-directories.

You will need full write/rename access to run this script. You can specify a UNC name in the $SourceDir and $DestinationDir variables.

Code above based on code sample found here http://www.marcvalk.net/2012/06/powershell-moving-files-into-subfolder-based-on-date/

Before – could be thousands of files

After – Files in neat subdirectories by date
