FPraw supports generic raw disk image files These can be handled by most disk imaging utilities and indeed many only support this format When FPraw tries to load a disk image it will actually fully load it into memory if the file is small enough this setting can be changed in the configuration file See Appendix B for more details on the configuration file FPraw does no format checking at all if you tell it to try and open a word document it will happily do so Because of this FPraw is the last plugin to be tried when attempting to open an image file FPzip FPzip provides support for compressed disk images which typically have the IMZ extension such as those produced by Winlmage Unlike FPraw FPzip is capable of storing a comment with the disk image and always regardless of size fully loads the uncompressed image into memory To see how to use the comment feature see Section 2 4 If FPzip is present it will be used as the default image format handler and IMZ will be the default file format when saving The files FPzip handles are just standard Zip files except they usually have a IMZ extension FPzip will only open zip files which have a single IMA file in them if there is more than one file or the file has a different extension FPzip will not load the disk image at all 5 2 PLUGIN LOADING 21 5 2 Plugin Loading On startup DIMG tries to load plugins using a number of default filenames trying each one until something lo
