What does one need to take care of when creating a method to move

What does one need to take care of when creating a method to move (cut) a batch of file from one directory to another?

Let’s say the method signature is Move(filter, sourceFolder, destinationFolder, overwrite). What do I need to take care of to avoid the risk of data loss especially when overwriting the original file and deleting of the source file is taken into account?

Several possible scenario I am worried of: error occurs when a move is in progress, moved a file but the file are somehow corrupted, deleted a namesake file in order to allow the new file to move but then error happens when moving the new file, etc.

I’m using .net’s System.IO namespace for the move operations.

    Without transactions, the safest way is to copy, verify and then delete. It is up to you if you want to move per file (this is how windows does it, a move operation can fail leaving you with half of the files moved) or to allow only the entire batch to be moved, or none at all.

    You would have to make decisions on how to respond to files that have been modified during the move, source files that cannot be deleted afterwards, or destination files that have already been opened when you’re performing a rollback.
