this is useful if you want to relocate only parts of a folder, say if you need to archive it, hand over to a client, or want to localise tagged collections to a new folder. these copies can then be moved to mass storage or be edited as truely independent projects: tagged collections on the other hand will only be links to the original files and thus edits will change the look of the image on the original folder too. such individually edited collections are useful if you want to give a calendar a consistent look (aspect ratio..?) or want to prepare a bunch of data is training data for neural networks.
input this data will all be ignored and discardedfilename : the filename to be written to disk. the extension will be preserved from the input.
