Which files (names) are missing from the disks?

Post by Debugger »

If I paste a list of filenames (full or partial[string]) into Everything, how do I check which names/files are missing from the disk?

I don't really understand how to combine this with a million characters on one line.

As a start, looks like you pasted the copied items into the Search bar.

Instead, "open" the filelist1:, & Paste the items into there.
Right click the filelist1: text in the search box and click Edit File List Slot....
Paste the filenames (Ctrl + V) and click OK.
so, you'll have,
o: filelist1:

& you physically hover the word,
filelist1:

right-click, Edit File List Slot...

This is useless, it doesn't do anything, and it doesn't show which names are missing from my disk. My question in the post was about something completely different! For example, if I paste 1000 partial file names

Code: Select all

xxx(xxx
, it should show that half of the names aren't on my disks.

It does not find partial names, and does not show names that are missing from folders on disks.

Not saying it will work or not work, only what I was told.
(And I've not gotten back to seeing if it will work for me - yet.)

As far as the partial name... I'm guessing there must be some function that would reduce the name to a "partial".
(Something similar to, seg$(x$,1,5), which would return the first 5 characters of x$ - but not in Everything.)

It's not possible to list filenames not found in your index with Everything.

You would have to write a script to test each filename in your list, see if it matches with a call to ES, and if it doesn't display the filename.

I am trying to find files that are missing from the Everything index by comparing a master file list against the output.
To achieve this, I wrote comparison scripts. However, the scripts fail and produce false results (either showing errors or skipping existing files) when dealing with complex filenames.

The main issues occur with:
1. Chinese characters (CJK Unicode).
2. Hidden characters / zero-width spaces.
3. Different types of Unicode brackets/parentheses that look identical but have different code points.

I went through this about fifteen years ago when cataloguing/playing MP3 files downloaded from YouTube. I Came to the conclusion that there were many agents (Windows. MSWord/VBA, WinAmp and so one which each could accept or refuse "strange" characters in fie names. I still believe that the whims of the innocent uploader in a langauge different from mine could contribute towards the mess.

My solution was to radicaly change the name of the file(s) at source.
