NEED HELP - Opening MacOS External On Windows 10

Hey all,

So I am moving to Windows 10 from MacOS but my WD external HDD is currently in use by MacOS and is formatted in exFAT - I have read this is readable by windows 10 and most of my files are .RAW images, Lightroom catalogues and word documents so they aren’t Mac restricted applications. I am wondering, if I open this on windows 10 will the external hard drive be readable? As I am selling my macbook tomorrow but my PC parts do not arrive till the 21st and I need an answer as I have files on my external that are vital to my business. Any help is appreciated, thanks!
