Our Verdict

One of the most coarse payoff I take heed about from readers — via e-mail or in theMacworld forums — is that their punishing driving are getting full and they ca n’t figure out what ’s conduct up all that infinite . The dim-witted result is to run a programme that examines your gruelling drive and shows you the biggest space - hog offenders . In the past tense , I ’ve recommended GrandPerspective and WhatSize , two fantabulous computer programme that do just that , although using different intro of the data : GrandPerspective creates a ocular representation of the blank each single file on your drive occupies , permit you see , graphically , what ’s taking up the most outer space ; WhatSize rather provides a size - grouped , hierarchical display that looks much like the Finder ’s column view .

But another unspoiled option isBaseline , which bid both graphic and columnlike views , along with a unequalled wrench . Like GrandPerspective and WhatSize , you could scan a volume at any time and regard the result . In List View , you could sieve by name , kind , adjustment date , size of it , or size difference of opinion ( more on the last option in a snatch ) . tower sight give you a hierarchal scene of your drive ’s contents . As with WhatSize , in both of these views , file and brochure sizes are colored free-base on size ; for deterrent example , the sizing for detail over 1 GB in size are displayed in loss , and the sizes of items over 1 MB but under 1 GB are purple . Baseline can even scan Time Machine volumes . ( As with any of these space - surveying programs , you ’ll require to run Baseline with ascendant prerogative to scan secret directories ; for exemplar , the dwelling folder of other user . )

One drawback of Baseline ’s Column view equate to WhatSize is that in my examination , the contents of each folder are n’t always sorted by size . On the other hand , Baseline includes Quick Look support — you could select a data file or folder in any view and then press the space prevention to see OS X ’s Quick Look prevue for that particular — and you could delete or press point right from within Baseline . ( A nice base hit lineament : If thenameof an point in List or Column view is purplish , that intend — in the developer ’s words — the item is “ cite in Apple or non - Apple software computer software that have been installed on your system . ” This means you should n’t mess up with that item . )

Baseline’s TreeMap view

Like GrandPerspective , Baseline also has a TreeMap ( graphical ) survey that shows every file on your drive represented by a proportionately - sized block or group of block . tap an token to see information about it , including yellow outlines that show you the “ boundaries ” of the selected item ’s parent folders . You also see , at the bottom of the windowpane , the path to the particular ; unfortunately , farseeing paths can be unmanageable to register , as the name of each folder are cut off to allow the full course to equip the breadth of the window . If you double - press an item in TreeMap view , the showing deepen to show a more - elaborated position of the contents of the next pamphlet down the Indian file pecking order .

Baseline ’s TreeMap view

My least - favorite part of Baseline ’s TreeMap vista is its grayscale presentation ; I find GrandPerspective ’s habit of color makes it easier to distinguish between files and to visually identify radical of exchangeable files ; for instance , photos or audio files . However , there ’s a grounds for Baseline ’s approach : the political platform uses colour to indicatechanges , and the power to expose such changes is Baseline ’s Orcinus orca feature .

Whenever you skim a bulk , the broadcast require if you want to make unnecessary that scan as a baseline . Assuming you do so , you may later use that scan as , well , abaselinefor comparability with a more - recent CAT scan . Baseline will then recite you not only the size of every Indian file and folder , but also how much each file cabinet and brochure has change since the previous baseline was saved . ( If you ’ve deliver multiple baseline , you’re able to liken the current scan to any of them . )

This is quite a useful feature ; after all , once you ’ve done an initial purging of your drive ’s contents , the next fourth dimension you use a programme like this , you really want to concentrate on just those file and folders that have changed . For instance , you could see how much your iTunes Library folder has acquire since you last scanned it . Or , if you run Baseline before and after installing a piece of software , you’re able to quickly see precisely which filing cabinet and folders were added or change during the install .

How changed items are pose bet on the view . In TreeMap ( in writing ) persuasion , Modern item and those that have increase in size are colored crimson ; the darker the red , the greater the proportional change from the premature CAT scan . detail that are low than they were in the premature CAT scan are demo in a violet - blue ; again , the sorry the colour , the swell the modification . In the image above , I ’ve compare the most - late scan of my boot bulk with a scan I performed back in April .

In List and Column views , clicking on Show Differences changes the Size newspaper column so that it instead displays thechangein size : positive numbers for items that have gotten big or are raw , negative numbers for items that have bring smaller or have been blue-pencil ( the names of the latter are colourize gray ) . you’re able to also clack on Show Changed to limit the display to only those item that have change since the previous scan .

In the image to the right wing , which show the content of / Usersin Column view , you may see that only my base folder and the divided up pamphlet have changed ; the former has increased in sizing by over 9 G , while the latter has shrink in size by nigh 134 G . Looking at the contents of the Shared folder , you’re able to see that much of that decrease came from the deletion of the iTunes Music folder ( which I had move to another volume since the previous scan ) .

Another unique Baseline feature is that the syllabus can generate a tilt of all matching data file on a particular volume . The physical process is obtuse — a Duplicates scan of my startup drive , which contains 167 GB of file , have nearly an hour to complete — but it works well , display a separate hierarchal list entry for each set of duplicate . Unlike some matching - searching utilities , Baseline scans the actual message of each file cabinet , disregard file name . And the Show Changed pick wreak here , too : you could choose to regard only those set of duplicates where file have change since the former baseline .

Unfortunately , the Duplicates lineament does n’t work across multiple volumes ; if you ’ve got photo distribute over three hard drives , Baseline wo n’t tell you which picture are the same . And it does n’t work on on file less than 512k in sizing , although unless you ’ve got 10 of 1000 of duplicates of that sizing , you ’re credibly not too interested about the amount of space they ’re taking up .

In plus to the minor issues I already mentioned , I come across a hemipteron where if you resize the Baseline window while in TreeMap prospect , sometimes the graphical blocks would no longer fit up with their pop - up entropy label . When this happened , I had to resize the window several more time to get the panorama to refresh right . I also occasionally experienced a trouble where , after scan a bulk , Baseline ’s contents horizon showed nothing but black ; mousing over that black area point a “ file ” called.com.apple.timemachine.supported .
