Will deleting Icloud Photos on File Explorer delete the photos on other devices.

When you have iCloud Photos enabled, any changes you make to your photo library on one device (adding, deleting, or organizing media) will reflect across all your devices connected to the same iCloud account.

If you delete the folder containing photos and videos on your computer, these items might be removed from your iCloud Photos library and subsequently from all your iCloud-connected devices. iCloud sync ensures that the media you see on your devices is consistent with what's in your iCloud storage.

Depending on your iCloud settings, if you delete media from your computer, iCloud might keep a lower-resolution version of the media in iCloud while freeing up space on your computer. This is part of the "Optimize Mac Storage" feature.

Deleted items might be recoverable from the "Recently Deleted" folder in iCloud for a limited time (usually 30 days) before being permanently removed.

If you don't want the media on your computer but want to keep it in iCloud, you can consider managing your iCloud storage directly from your devices or through the iCloud website.
