'''Disk Image Archiver''' (stylized as '''Disk IMage Archiver'''), or '''DIM''', is a shareware disk imaging utility for PC DOS developed by Ray (Arsen) Arachelian. Disk images can be created as regular data files. Optionally, a password can be specified to protect the disk image contents, although the encryption method is said to not to be very secure. A companion tool, '''MKSFXDIM''', can convert these files into self-extracting executable modules; however, encrypted disk images are not supported. Versions of the software other than 1.4a seem to have disappeared and sample files are very hard to find.

== Identification ==

Disk image files start with the ASCII text <code>Disk IMage VER 1.0 Copyright (C) 1992 Ray Arachelian, All Rights Reserved.</code>, but checking <code>Disk IMage VER </code> (hexadecimal {{magic|44 69 73 6b 20 49 4d 61 67 65 20 56 45 52 20}}) should be enough<ref>[https://file-extension.net/seeker/file_extension_dim File extension DIM details at File Extension Seeker]</ref>.

Executable self-extracting images start with an [[MS-DOS EXE]] header. Previously mentioned signature should be found somewhere from the start of the overlay segment (see [[MS-DOS_EXE#Special_file_positions]] for reference). A signature in the TrID database<ref>[https://file-extension.net/seeker/file_extension_exe File extension EXE details at File Extension Seeker]</ref> matches the EXE header from SFX executables created by MKSFXDIM.EXE V1.3, which is included in the DIM 1.4a distribution package.
