Hi All. Greetings and salutations from @mACA!z Infoz & Newz...
Imagine that you receive an e-mail like this in the photo above with greetings and salutations on Windows environment and imagine that you click the icon attached...Well, before this click you starts your favorite antivirus and take easy: no viruses found! Now you click the icon. Hehehehe....In seconds your entire C partition is deleted....I tested this "bomb"on Windows 2000 Professional and this new, improved and enhanced operating system build for the new millennium have not any protection versus deltree irrecoverable actions if the user decides format his partition using FAT!!!

TO SEE OS/2 DELTREE AND ELIMDIR CLICK HERE

 Warning! Some jackass are sending this ruinous e-mail and the disaster it's possible just because Microsoft doesn't provides any protection versus this mortal combination: deltree + shortcut = .pif if the user received it on Windows 95, Windows 98 or Windows NT formated in FAT, running in the same partition where resides Windows 95-companion. To prevent the disaster don't click any attachment received without a precedent inspection of the properties of the object! If it is a .pif file can be a bomb! Opening the properties you can see the command line and if the command line is <C:\WINDOWS\COMMAND\DELTREE.EXE /Y C:\*.*> or similar, don't click the object! Catch it without click and drag it to the Recycle Bin and empty it!

The next photos shows how the e-mail bomb is created on Windows desktop by any idiot, step by step! (I used Windows NT4 SP6, one of my beta test machines for made these screenshots below):

1 - CREATE NEW SHORTCUT

 2 - INSERT A COMMAND LINE

3 - SELECT A NAME...

4 - CHOOSE A NICE ICON....

5 - THE BOMB IS CREATED!

What is Deltree

Photo above shows DELTREE options and warning note on @Macarlo's Windows 95 prompt

The Windows NT (New Technology) have not the DELTREE.EXE as a native program. Deltree is a DOS program. Windows NT have not any DOS. The icon used by Microsoft for call the Windows NT Command Line (Console) is the same icon used for call MS-DOS prompt on Windows 95/98 and sincerelly I've not encountered a reason for this allegory. Windows NT have a shell fopr Console that emulates some DOS functions, but is not a DOS and have not any Deltree. If you ask Windows NT on help about Deltree (deltree /?) at the prompt NT simply saids that don't know Deltree...The problem is the NT users have the habit of install also Windows 95 on the same partition, if he are using FAT. The original Windows NT CD from Microsoft contains a compact Windows 95 release for to be NT partner on the same partition. And Windows 95 have deltree as a native program...I suppose that Microsoft doesn't make any protection for deltree's disaster because Microsoft are interested in force the user to join NTFS or NTFS5. If the user join this format he stay captive of Microsoft because other operating systems can't access partitions formated with this file system.

Deltree is a very powerful program and it can delete entire trees in irrecoverable mode; just because this ability it was named Deltree (delete tree). But deltree is not only a DOS program in other operating systems, as OS/2. IBM not made a deltree for OS/2 as a native program, but exist several versions from developers as M. Kimes, author of famous and awwarded winninf FM/2 file manager, and with other name, as ElimDir, developed by Anthony Pereira, author of Disk Jockey file manager (for OS/2 and Windows 32 bits) and included in the pack called Performance Plus (I'm registered user of Performance Plus and use it on Warp 4.0; the boxed version was sent to me as a gift by the computer guru Renee Senger). Deltree for OS/2 can delete entire trees on FAT or HPFS partition but can't be started by a Windows pif created as a shortcut because it call for the DOS environment and OS/2 have not an authentic DOS (the OS/2 DOS is only a DOS emulation without Deltree} Some brazilian OS/2 users engaged in the Free OS project based in OS/2 Warp are writing, compiling and testing some Deltree versions projected for run in the command line of this new OS as native feature.
