Deleting a document from one of "My Folders"

Will the document disappear from packages where it was used? Yes, we honor the request for deleting the files out of the system. We try to give sufficient warning in our system. Anytime something is going to be deleted, our system will always ask if they are sure they want to delete the file and inform that it cannot be undone. 

If you delete a sheet from your My Folders area and then realize you need it on an older package, you'll just need to upload another sheet and use it on that package.

Regards!
