What do I do with old iTunes folders? Is it safe to delete them?

I learned something that you may be aware of, that there are different things you can do before deleting a file or folder as a precaution. I suggest renaming a file or folder and then rebooting your system worst case scenario your system may not boot! depending on the file you you renamed! But at least you’ll be able to boot from an external device and rename the file or folder back to what it was. OR If you have dozens of files you can make a temporary folder and move all the files inside the folder so the system doesn’t see them at all if it works for a week or so without a problem you may delete them but be very careful! As a general rule if a file is known as a system hidden or read-only I won’t touch it in most cases.

finally as a standard disclaimer I am not a technician, just someone who enjoys computers so take my advice at your own risk because I can’t promise you this would prove harmless to you or your system.

good luck!

PS I have found sometimes to the PC may find the file you renamed or moved and use it from its new location so beware!

Well since they’re not being used at the moment and your PC use running satisfactorily I would guess that you’re OK deleting it but do you really need that space that bad if so delete it and cross your fingers if you can spare the space that it’s taking leave it alone. I’d also like to mention that it is possible that there’s some obscure app or utility you haven’t used it since moving the files so there’s been no issue, but if that’s true Then eventually you may run into a problem if you use that obscure app. Once again good luck!

You never know what will happen if the computer comes across a file it needs and is missing. The computer may just throw up an error telling you we can’t load the happen question but it may also just stop everything and freeze the screen. That’s why I say you need to be careful.
