What is an FXF file?

An FXF file is a data file created by BigFix, a suite of software programs used to manage systems security and software updates. It contains an action that is sent from the BigFix Console to the BigFix Server.

More Information

FXF files are typically 5K to 20K in size. Files over 20K may cause the error "Unable to send to socket during POST operation" and should be reduced. Some examples of BigFix action files include Analysis 147.fxf, Fixlet 146.fxf, and Action 148.fxf.

NOTE: IBM sold BigFix to HCL in 2019.


The file "TROJ_FAKEAV.FXF" is not a BigFix action file, but a trojan horse that may be installed with malware. This file should be removed with antivirus software or deleted immediately.
