This section explains what each column in the TreeView means and how you can use it. If you want to customize the TreeView you can use the Tree Options in the Input Specifications area.
Directory Name
This column holds the name of the directory. It is usually the name of just the current directory - but it can be changed to show the entire path name as well.
Size
This column shows the total size of the files in that directory structure or individual directory. This file size is obtained by adding all the individual file sizes.
Compressed
This column shows the total size of the files - taking into account any files that were compressed - either individually or because they were in a compressed folder or drive.
Actual Size
This column shows the actual space taken up by the file on the disk. It uses the Block (or cluster) size to calculate this value. Basically a block is the smallest piece of disk space that can be allocated. So for example if you have a NTFS partition with a block size of 4 KB - then the smallest piece of disk space you can store a file in is 4KB. Thus a 10 byte file (ie. a file with say 10 characters in it) would still take up 4 KB of actual disk space - even though it is actually much smaller than that.
NOTE: For Offline files - the actual size will be the size of one Block or Cluster. This is all the space taken up with the link to the off-line data.
Wasted Space
This column is a calculation of the space "wasted" due to block sizes on your disk. This used to be a huge issue with FAT (and even FAT32) file systems - but has become less important with NTFS and other more modern file systems. Wasted space here is meant to show the amount of space that is "lost" between the true size of a file and the actual size of the file on the disk (which must be stored in full blocks). So - in the above example the 10 byte file stored in the 4 KB block would have the following calculation done to show Wasted Space. 4 KB = 4096 Bytes. 4096 bytes Actual Space subtract 10 bytes of file space gives 4086 of "wasted" space.
No. of Files
This column shows the total number of files in that directory structure or individual directory.
No. of SubDirs
This shows the total number of directories - not just the subdirectories in the that branch of the tree.
Owner
This column shows the owner of that particular directory.
Last Create Date
Last Modified Date
Last Accessed Date
These three columns show the last day a file was created, modified or accessed in that directory branch. This is an important difference as those dates for directories in Windows Explorer are pretty much useless. As Disk Triage scans the directories it gathers information on what was the most recent date that a file was created, modified or accessed and stores it in the tree. This allows the user to quickly see at a glance the approximate age of the contents of that directory structure. It records this for each directory for both the individual directory level the entire directory structure.
Created Activity Size
Created Activity Files
Modified Activity Size
Modified Activity Files
Accessed Activity Size
Accessed Activity Files
These columns measure the basic Activity in the directory structure for a certain period of time. In the Basic Input Specificiations section you can choose whether to gather Activity Stats or not. In the Tree Options section you can choose either to gather them by the last 'X' days or between two particular dates. In either case this feature will show you both the number of files and the total size of the files that have been created, modified and accessed in that time period.
This is a great way of seeing how much activity has occurred during a time period. When used in combination with the "Last" Dates above - it provides a better picture of the over all activity and age of your directory structures. The "Last" dates will tell you the approximate "age" of the contents of a directory - but you don't know how much activity has occurred there. These columns provide that missing information! For example if a directory shows as having had content in it modified as of yesterday - you can now look at the Activity columns and see how much as been changed in the last 'X' days.
