FILExt - The File Extension Source

Details for file extension .GRF are on this page. Because there is no central registry for file extensions and their associated programs there may be multiple entries on this page. And, because there are many (some say over a million) such associations not all may be listed here. A search on the file extension you submitted shows 12 record(s).

Graph Plus Drawing		Corel
Specific Notes [What's This?]
This is an old graphics file format. It started out as a Micrografx format under the program Graph Plus. The end of Oct, 2001, Corel bought Micrografx which, by then, had dropped the Graph Plus product. The format is similar to the DRW graphics format. This format was sometimes used to transfer graphic files into Charisma and as a native Charisma format as well. [Search for GRF file errors with this scan.]

System Info for File Extension .GRF

FILExt has been given permission to display the file extension database produced by the Associate This! program. Some of that data has already been included into the main FILExt database; but, not all. Those entries which have not yet been incorporated are shown below in the hope that they will be of some use. Data collected by FILExt on registered file extensions from user systems is also in the display. Be aware this is raw data which may require further research on your part to fully understand. In particular, look at the Program ID. Often a company will put the program's name into the short ID that Windows uses to open registered file extensions. If that's not the case, look at the complete path to the EXE file. Often, programs will install themselves into directories that give either the program or company name. The program name itself may also be used as the EXE file name. These listings are particularly important since they represent listings that are in actual use by users who have sumbitted data to FILExt and therefore these listings can point you to the most likely candidate should there be multiple entries in the FILExt main database.

General Info

• If the extension you are looking for is of the form .??_ the file is likely a compressed file and part of an install routine. When the install program runs it will expand the file and replace the underscore with the proper letter for the file type.
• If the file is sent as an audio file with any three-character extension it may be a dictation file where the extension is the dictator's initials; playable by BCB Voice Systems software (see ??? extension). The file could likewise be a dictation file in TrueSpeech format. Use Windows Sound Recorder and/or Media Player to play these back.
• If the extension you are looking for has a number at the end or is only a number and there were no results consider entering the same extension format using zero or one as some programs produce numbered split files but when the split can be extensive (e.g., .000-.999) only the first entry is in the database.
