You can try this one to try
it has a free trial so you can see if it is there to recover. The longer something has been gone and the fuller your disk drive is the more likely that something has written over part or all of the file and it will not be recoverable at that point
I attempted to use both Data Rescue 3, and Disk Warrior with no result. From my ongoing research about how the filesystem works, once the Trash is emptied, especially with an encrypted disk image, its gone.
Well, it seems that I answered my own question. Thanks.
yes I am very sorry about that but you never told me the drive was encrypted.
recovering deleted files is never a sure thing because as far as the operating system is concerned they are gone. Its just that sometimes programs can take advantage of the fact that they don't actually delete them until they go to re use the space. But the encryption does what it is designed to do and wont let anything read the drive outside of the operating system with the right person logged in.
I am sorry that you feel I gave you poor service. Please tell me what you think I could have done better given that you deleted a file from your computer, removed it from the trash bin and were working on an encrypted drive ( which you neglected to tell me )
