Help Retrieving files from SD card without formatting.

[Murtholemu]

Hi,

New to the site so please forgive my etiquette. I have an sd card that my phone is saying I have to format in order to use. But I have some seriously important files on there that I need to retrieve first and the SD card reader on my PC is for the larger format. Is there any way at all to retrieve said files without getting a converter/adapter for the reader on my PC?
I won't be able to get an app on my mobile due to having no memory for even a chrome update since updating the OS a few months back.

Thanks in advance!
