Recombining split files

Data may be transferred in split files, which will commonly have the extension .bin or simply .001, .002, .003, etc.. These files can be re-combined into the .RAR format, a common archive format similar to .zip. You can use a command in DOS to recombine these binary files into a single .RAR file that can be opened.

copy /b splitfile1.bin + spiltfile2.bin "2019LItSupport.rar"

Two files, 'splitfile1.bin' and 'splitfile2.bin' from separate discs or downloads, become a single rar file that can be opened in WinRAR or 7-zip.

7-zip also contains a utility to re-combine split files but WinRAR does not.

Windows Explorer won't change directories

In Windows 10, I've found that the old, reliable cd command [to change directories] doesn't always work. If it fails for you, try following the cd command with the operator /d and then list the path of the new directory. This will allow the drive and directory to be changed at the same time.

-extoff command

If you’re having trouble opening a program in Windows, you can use a simple trick to get the software to run. In Windows command prompt enter the path to the executable file followed by “-extoff”

This will let the program run with any extensions disabled.
