John,
See a previous discussion on this from this past November... not sure if this link to it will work, but ...
http://www.amazingcharts.com/ub/ubb...ying_to_delete_imported_i#Post11316items)
In summary, we found that choosing to delete the imported item doesn't remove the actual actual file from the patient's imported items FOLDER if that item is being "previewed" in the imported items page of AmazingCharts, but if another (or no) item is previewed, it does delete it.
Besides saving space on the drive/folder, I think it is important to really delete these files for items that were imported in error (wrong patient)... that way, if ever the patient needed their records, there won't be any chance of them getting info that didn't belong in their chart.
