With Omaculate
Omaculate doesn’t offer to trash big files by default, because big files are often the important ones. You can still write a recipe with "is over 1 GB" if you want Oma to list them; anything bound for the Trash waits for your approval.
Usually installers, video files and zips. A few disk images and screen recordings can add up to many gigabytes.
Not until you empty the Trash. Files in the Trash still take up space on your disk.
Free for one folder. Everything free for 3 days, then Grand Oma is $14.99, once.
