   FileInvert - a free tool to invert all of the bits in a file.






FileInvert Program

Description/Download










A simple tool to invert the bits in any file.  This is free software and is provided free of charge, 'as is' with no warranty.  No registration required. 

Faced with a file of data taken from an EPROM, where the bits had been wrongly copied, so every '1' was '0', and every '0' was stored as a '1', this simple program was produced.  Used exactly once, it did it's job and hasn't been required since.  But it is provided here free of charge, in case someone else has a similar problem, to avoid them having to reinvent the wheel. 

There is no installer for this program, just unzip the executable and run it as necessary.  Select the input file, select the output file where the result is to be written, and press INVERT to begin the conversion.  It has not been extensively tested, but was able to convert a 4GB file on Windows 7 without hiccup. 

FileInvert version 2.0, released October 2017, the simple program has been updated with a progress dialog and improved error reporting.  Can now also be run from a command line, type command "FileInvert2 -h" to get help on command line format and options.
