New Release: 3.0.1 Beta 2

[Xanashi]

i am using zip version in drive d. i cannot set set location to any folder on drive d. it always gives error "selected fodler doesnt have the proper read/write permissions". but i can copy/dlete anything on that folder.

Oh, I recall the problem now.
I'll have to read up on some of the previous threads about this. Then revisit the issue.

2. How did you get epub files to thumbnail? :D
I'm pretty sure I haven't added that format to Icaros yet. *scratching head*

Well well well... I was going to wait until the dust settled on Beta 2 before asking for that feature!

Someone earlier said this:

You can also set the "epub" extension for Icaros thumbnail previews of image files (usually the book cover) contained inside of an ePub book, as this file format also uses zip compression.

But I'm sure it's more complex than that...

Good news! It really wasn't more complex than that. :D
Most Epub files have a similar structure (archive with images inside), so adding epub to Icaros is straight forward.
I'm going to add the extension to the upcoming release of Icaros.

1. Oh wow, thanks for the guide.. I didnt know that..
2. I just added 'epub' to thumbnail filetypes.. forget it then..
3. Well the explorer just freeze and I cant do anything in the folder (thumbnail generated but freeze halfway, cant delete/copy/move)
But, it works fine now after I clear the caches and restart.. >.>
From my guess the problem caused by pdf handlers from 'PDF Preview for Windows 10'.. I was trying to get thumbnail for my pdfs files, so I downloaded this program..

btw, SumatraPDF installer type can generate thumbnails for pdfs in win10?
I used SumatraPDF (portable) myself..

1. No problem, hope it works for you!

2. After some testing, I can confirm that epub files work pretty will with the current version of Icaros. :)
I will be adding it as a default format to the next release of Icaros.

3. Okay, let me know if you have any further issues with this. And if you think Icaros is involved in any way.

I too use the SumatraPDF portable version, so I haven't actually tried their shell extension yet,
but as far as I can tell from their website, if you use the installer to install Sumatra, you get the option 
to install their shell extension as well. And it should work on Windows 10.

Thanks a lot. It works well for me.
But some of the webp format images showed video thumbnails, this may make me confused. How can i cancel it but don't affect common video?
My native language is not English, sorry for my broken English.

OS:Windows 10 x64

That's actually my bad. Webp files should be registered by Icaros as an image format, but they're currently not.
I'll be fixing this in one of the next releases of Icaros, but for now please grab the attached reg-file and 
double-click it to fix the issue.

Once you have 'merged' the file with your registry, open IcarosConfig, go to the Tools page, and click 'Refresh'.
That should make your thumbnails appear correctly.

Can you explain better the differences between dynamic and static? i read the tooltips and couldn't understand.. does Dynamic saves the cache on Windows Explore and Static saves it on the folder you selected on Icaros?

To understand these two cache states, a bit of information about the Icaros cache itself is probably needed.
Here's an excerpt from the Icaros README:


Icaros Cache
===========================

The Icaros Cache was implemented as a counteract to the issue where Windows deletes its own thumbnail cache.

If the Icaros Cache is enabled, Icaros will be able to store a copy of any thumbnail in an internal cache, and if for some reason
Explorer deletes its own thumbnail cache, Icaros will be able to regenerate all the thumbnails again at almost instant speed.

If the Cache is disabled, it wont have any impact on the thumbnail provider at all. The thumbnail provider will just work like
it did in previous versions of Icaros.

The cache was designed to deliver thumbnails to Explorer at the highest possible speed, however Explorer still needs to process
each thumbnail (i.e. validate, crop, apply adornments, and add it to the Windows cache), so you may still experience a small
rendering delay even when the cache is used.


The Icaros Cache can be utilized and managed in a number of ways. Below is a quick walkthrough.


1. The Icaros Cache has 3 activation states:

    - Disabled:                 Cache disabled
    - Enabled (Static):      Icaros Thumbnail Provider will use the cache, but without adding any new entries to it. IcarosConfig can still modify the cache (see below).
    - Enabled (Dynamic):  Icaros Thumbnail Provider will use the cache, and add new entries to it dynamically, as it thumbnails files that are not yet cached.

...


The README does contain additional information on how the cache indexer and other cache features works, but this was a question about the states,
so I'll limit my response to talk about that.

As described in the above excerpt, if the static state is set, Icaros will continue to grab thumbnails from the cache when possible, but it wont add any new
thumbnails to the cache and thereby increase its size.

If the dynamic state is set, Icaros will both grab existing thumbnails from the cache when possible, but also add any new thumbnails Icaros generates to
the cache. 

Most users will probably get most out of having the dynamic state set, but for users that require more fine control or only wishes the cache to contain
thumbnails that are added by the indexer, the static state may be preferred.

Hope that answers your question. :)

Thank you for your hard work!

Is there any chance that one day Icaros could entirely replace windows cache?  On my 4K monitor thumbnails are so tiny, especially of 16:9 videos and unfortunately windows cache does not allow sizes larger then 256 x 256.
