I know there's been a discussion going on about compression utilities, and I've found it very informative. I am interested in purchasing one of two utilites, either AutoDoubler (AD) or More Disk Space (MDS), and I have some specific questions about the two. In a recent MacWorld Article, David Pogue compared many different compression programs, including DiskDoubler and Superdisk. He raised some pros and cons about both, and I want to ask if those also apply to AD & MDS. 1) Does AD or MDS change a file's type? If the file's type is changed, "utilities like On Location and Disinfectant can't read their contents." This also means that you can't compress things like After Dark modules and Word dictionaries (according to Pogue). Also, I would want to be able to use Symantec Antivirus for Mac to scan a disk with compressed applications, is this possible with AD or MDS? 2) Does AD or MDS check for file integrity after compression (checksum)? Pogue complained that Superdisk didn't check data integrity, so this question is directed more toward MDS. 3) Does AD or MDS delete a file before saving the compressed verstion? Again, directed at MDS, since Superdisk did this (bye bye file if power went down before Superdisk was done). 4) Does AD or MDS change a file's icon after compression? Purely a question of aesthetics. 5) MDS states that it uses some type of standard compression, and this means that a file can be decompressed without MDS being present. Is this true? If so, how "standard" is this algorithm (ie are they using an algorithm Apple will support in future system releases)? I am leaning toward AD, and I am very interested to see if it addresses any of the issues listed above. Thanks in advance Mark Bubien -- Mark Bubien, Voice: (619) 931-2695 Pre-Press Technologies.
