Extension: EFW
Program and/or Extension Function [What's This?]		Company [What's This?]
CA Security Center Renamed ZIP or EXE or RAR File		CA
Specific Notes [What's This?]
Use an editor to look at the first two characters in the file. If they are PK then the file is a renamed ZIP file; if MZ then the file is a renamed EXE file; if Rar! then the file is a renamed RAR file. Rename the file accordingly and then either use an archive utility like 7-Zip to open the file or run it as a program. Be VERY careful with these files as an anti-virus program has renamed them for some reason. They could be infected. Recommended: Find EFW errors now.

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.
