Unknown folders on external drive?

Recently, in one of my external hard drives, the following folders have appeared in the drive root:

7fb7dac2bb16c4aa9c7238e97b5bcc7c empty

65c8d890d8d994d8302e43b3f93c empty

531a420f86442b4ff51cdb7b 'Setup.exe' inside

629d83dea8849fbf3adb1b have to open with 'admin', folder 'amd64' inside

ab9251f6adfb6282d66a83a8 have to open with 'admin', folder 'amd64' inside

b8854913dead8cf1a6

Anyone know how and why they appeared, what they are for, and is it safe to delete them?

Thanks!

Win 7 64bit

They are temp files from install often if you Google the number it will tell you the app. The best option is to rename or copy them leave a week if everything works delete this way you can role back if something doesn't work

Thanks everyone for your fast responses. Once a month I run CCleaner....the next time I run it, I'll see if those folders are 'cleaned'.

Uncleaner is best tool
