Request: about:ext-survey -- File extension forum survey.

Post by raccoon »

Dear Void,

I would like to conduct a forum survey of willing participants to help better identify popular file extensions in the wild, at least within our small sample group. This will help to give us a glimpse into which file extensions are most prevalent (by rank), and which if any are missing from the default Filters included in Everything.

Could you add the Search Command about:ext-survey that will scan the user's index for regex:(\.\S{1,12}$) and tally each unique file extension, and then convert that raw tally into a ratio of the total file count, from 0.0001 to 0.9999. Example:

Code: Select all

.jpg 0.5611
.png 0.2792
.mp4 0.1446
.xlsx 0.0199
.mkv 0.0170
.xls 0.0068
.tar.gz 0.0026
.exe 0.0014
... you get the idea. We can then add all these numbers together between multiple submissions and arrive at a tidy list of file extensions ranked by relative commonality. Not completely scientific but still useful.

about:ext-survey would need to provide a mechanism to copy the results to the clipboard, and should include the bbcode \[code\] block.

Bonus: Add the Windows Registry description of the file extension if it has one.

Code: Select all

.xlsx 0.0068 Microsoft Excel Worksheet
.exe 0.0014 Application

Done.

I had some existing code around to do this already.
I used extension frequency to look into database compression.

I need some input on constraints..

Maximum number of extensions. -I've set the default to 999 which seems fine.
Minimum number of times the extension occurs to be included. -I've set the default to 100.
Maximum extension length. -I've set the default to 6.

I have privacy concerns, for example: file.private-data would leak private-data.
Restricting the maximum extension length to 6 would mitigate the issue.
I would like the survey to be anonymous.
Users could post the results here:
https://www.voidtools.com/contact/
with email set to ext-survey
I could then post the results here.

The total file count can be inferred from the last extension, since the count will be around 100.

I compiled my own results last night using Notepad++ and some scripts. I'll send you my full results with 12 character length extensions. Mind that I have 30 years of old files slopped from every old harddrive I've owned and my parents owned onto new harddrives. Sent to https://www.voidtools.com/contact/

Looking at my data, I'm having second thoughts about the approach of total number of instances alone, and I think relative total byte size may be a necessary metric. Exclude 001 002 003 in case someone wants to remove a line anonymously.

Code: Select all

;rank size ext description
0.143637 0.000628 dll Application Extension
A huge swath of file extensions are just nonsensical software package support files, such as language translations, manifests, document templates, brushes, and all sorts of browser and cross-platform software (Linux on Windows) library stuff. Millions of tiny files that consume almost no disk space.

Maybe exclude any file extensions that do not have a registry entry. If the user isn't using a file viewer, they probably don't want a filter for those files? Knowing the registry entry will help you group files by filter type. Eg, LibreOffice Files.

If having the data sent directly to you, I don't know if limits should be necessary, or they should be loosened. Survey all the extensions, it's voluntary. That may be the only way to spot really unnecessary Filter defaults that don't benefit anyone.

Exclude entries with the @ symbol in case of really short email addresses.

I had 10,428 results. 5,005 with 2+ occurrences. 2,842 with 3+. 2,529 with 4+. 2,186 with 5+. 1,000 had 29+ occurrences, but I only have 26 *.arj and 20 *.ace (Compressed) files that would have been omitted from your proposed constraints.

Can this become an Extension Sidebar? :)

Thanks for the link NotNull,

Looks like Everything is using most of the common file types from https://fileinfo.com/filetypes/common already.


Maybe exclude any file extensions that do not have a registry entry
This was how most of the default filters were generated for Everything 1.5.
I used HKEY_CLASSES_ROOT to build a list of well known extensions from a fresh Windows 10 install.

Everything 1.5.0.1291a adds an about:ext-survey search command.

As you can see I mainly index raw image files (.NEF) and their side car files (.xmp) that are stored on net shares. However the vast majority of the files are tiny short link files (.lnk) that I use to map tags stored in .xmp files into a huge folder tree. Not very elegant but it works. [sigh] I have plans to map the tags into proxy .jpg proxy files instead that are supported by ET.

An alternative approach is to compile statistics on which extensions are acted upon in some way by the user (double or right-clicked/dragged/renamed etc) since this will usually target what they are actually seeking.
It could even use this to offer adjusted filters to each individual without uploading any results, though a manual upload could send it in.

(IMO... a default is a default. And a user can add or remove as their needs dictate & change.
"Acted upon" isn't really relevant, necessarily, as files may just "be" & are never "acted on", or if so, are acted on completely outside of Everything. [Yes, I know, that is unheard of, but ;-).])

(BTW, my list is what void posted above. I can tell, at this later time, by reading down it ;-).
And the listed frequencies are not indicative of what I do, or don't do, with said extensions.)

How long should this survey be part of Everything?

I learned what I needed to. I still think it would be useful information to @void if he collected this data, but also collected the file type program associations to get a better idea of what software opens/plays/views what filetypes, to round off the default filters of extensions used by leading software.

I'll remove the survey in the next alpha update.

Thank you to those that participated.

To quickly find extension frequencies in Everything, please try the following search:

add-columns:Extension;"Extension Frequency" distinct:"Extension" sort:"Extension Frequency"
