Frequently Asked Questions
Q: I am trying to compress a file and it doesn't get as small as I had hoped. Am I doing something wrong?
A:Some files compress better than others. Many multimedia files are already compressed using lossy compression. That means they sacrifice resolution for size reduction. Such is the case for jpeg, gif, mpeg, mp3 and many more. These files often cannot be compressed any further, by any compression software.
You may get some further compression on certain lossy compressed files if you switch from DropZip to DropStuff or StuffIt Deluxe and make StuffIt X (.sitx) or StuffIt (.sit) files. If you attempt this, be sure to set your StuffIt preferences so that the Compression level is set to Better Compression and also uncheck the box that says "Do not compress files that are already compressed".
Uncompressed multimedia formats such as .wav (audio) and many high resolution graphics such as .psd (native PhotoShop picture), .eps (postscript graphics), and uncompressed tiff files will compress quite well. In fact, if you are starting out with a high resolution graphic you may get a smaller file by stuffing than by converting to jpeg or gif.
Be sure to set your StuffIt preferences so that the Compression level is set to Maximum or Best Compression and also uncheck the box that says "Do not compress files that are already compressed".
Q: I have a password protected file for which I have forgotten the password. What can be done?
A: There is nothing that we can do in this case: the contents of your file has been encrypted based on the password you provided, it cannot be decrypted without this password. There is no "backdoor", and we are not aware of any weakness that would allow you to break the encryption, short of trying all possible passwords. We apologize if this has caused you to loose an important file, but encryption would be a worthless feature if it could easily by removed.
