Accidentally deleted the software on my Passport Wireless

I’m an old fart so bear with me…
Passport was working fine. Then I wanted to delete some files. I deleted the software.
I know that I can get and reinstall the software; however, if I do, will that delete all of the documents that are now backed up on my Passport?

Read how to restore backup for complete user manual for your device. You likely deleted it from the device, so download it from WD Support site.
