Understanding search for Empty FILES

[ChrisGreaves]

Please see also Understanding search for Empty FOLDERS
I am still a New User and want to obtain a list of files that are empty; in this sense by empty I mean ZERO bytes on disk.

Code: Select all

T: file: !size:>0

I am looking only at my data partition drive T:
I am looking specifically for files, not folders.
And NOT files whose size in bytes is Greater Than zero. I carried this over from the topic Understanding search for Empty FOLDERS, but I am still digesting that topic.

Selecting all the files (Ctrl+A) and then pressing Alt+Enter brings up a Windows Explorer pane as a check:-

I have noted that I have three files which, at times, I might consider "Empty"

EmptyFolder_03.png

The MSWord2003 DOCument and the Excel2003 workbook resulted from loading those applications and immediately using File, saveAs without doing any work at all.
Cheers, Chris

Consider using the content: or fromdisk:content functions to find out if these files do not contain visible text.
(regarding visible: defined macros or pictures will not be detected, so might be tricky to be certain)

Please use size:0 for files.

!childsize:>0 is only needed for folders because this search is applied to each child file. -any child file that matches will cause the folder to match.
!childsize:>0 will be replaced with totalchildsize:0 in 1384a+



To find files with no content:

t: file: !content:

This will match binary files too, I recommend using it with a document filter:

t: doc: !content:

Everything 1.5.0.1384a replaces child-size: with total-child-size:
