Alan al­most finds it fun to man­age stor­age with this util­ity

There are sev­eral ways you can get a breakdown of what’s us­ing up your Mac’s stor­age in or­der to work out what to archive or trash. Open­ing the Fin­der’s In­spec­tor win­dow gives a cu­mu­la­tive to­tal for what’s se­lected, but it can be slow to run cal­cu­la­tions. Al­ter­na­tively, there’s GrandPer­spec­tive, a free tool we talked about in MF292. DaisyDisk (£7.99) is our favourite, though.

In or­der to show disk us­age right down to your Mac’s deep­est fold­ers, DaisyDisk first has to scan a drive’s file sys­tem. Pre­vi­ously this could take min­utes, but the re­cently-re­leased ver­sion 4 re­lieves this frus­tra­tion – it­self a mi­nor bar­rier to get­ting on with work when you’re run­ning very low on space. It’s or­ders of mag­ni­tude faster, scan­ning our al­most full 512GB SSD in sec­onds.

DaisyDisk’s pretty rep­re­sen­ta­tion of how your stor­age has been used is also prac­ti­cal. Its in­ner­most ring rep­re­sents the cur­rent folder, and outer ones are its sub­fold­ers. The size of each sub­folder is shown in a key on the right, and each seg­ment’s rel­a­tive size gives clues as to where to start look­ing for space hogs. As you browse a drive, items can be added to the Col­lec­tor. Th­ese de­ci­sions can be re­scinded, and if you press Delete, you get a brief chance to can­cel it.

DaisyDisk quickly proves its worth on to­day’s Macs with flash stor­age, where lim­ited ca­pac­ity can fre­quently run out.
