WizTree is an attractive, fast, graphical display of HD contents
This free software has been developed in New Zealand. When I saw the results of my first hard drive scan, the colourful graphical representation of the contents seemed very familiar. A much older version, perhaps by another name, existed back in XP days. However, the current version 3.41 was last updated on May 5, 2021, with fixes and updates occurring regularly.
Any drive formatted NTFS has a Master File Table, readable by WizTree, allowing very fast completion of the scan. My 1 TB hard drive, a little over half full, took only 7 seconds. A 128 GB SD card, inserted in the laptop, took 0.28 seconds. The 70 GB used up on a 1 TB USB 3.1 SSD, scanned in almost zero seconds.
So, I tried some network connected drives. The 80 percent full 4 TB Synology NAS is NTSF, so took only 72 seconds to scan. However, two other NAS drives were likely formatted with Linux. The 2 TB Western Digital Home took 8 minutes, and the older 1 TB Raid 1 D-Link NAS (reporting as Windows NT server OS) took 9 minutes (on a gigabyte network).
The rectangular, vibrantly coloured "pillows" at the bottom of the display, convey a lot of information. Each colour matches a file type and its size represents the amount of space taken up on the drive. The location of each "pillow" is also relevant, indicating the proximity of each file in the tree structure. Also, hovering over a "pillow" brings up informative tool tips. The left panel shows, in descending order, files taking up the most space. If you see a file taking up way too much space, or you are positive two files are the same, deleting unwanted files can be done at this time, within WizTree.
Right clicking on a "pillow" (my word) in the left panel should bring up all of the context menu items already installed / configured with the account. One of those menu items will be 'Delete'. As the left tree view folders are opened, users will see more graphical filesize displays.
Right clicking a colour in the right panel allows selecting all files of the same type (white border appears around all files of the same type / colour).
Another option exports the tree(s) as a spreadsheet text file (CVS), with comma delimiters. I tried importing one into Calc, and it worked well. You might do this to make a record of files when putting a drive away in a secure storage location.
