Here's to USB 3.0, i can't wait to be able to copy stuff like this and not go nuts.

It's taking quite a long time :/

I was able to get this down to 60.7 MB; here's how I did it.
Standard legal disclaimer: Note that this isn't official advice, and I can't be held accountable if something goes wrong.

First, delete ADPT.exe and ADPT_Mini.exe; leave pt_explorer.exe alone.
Then, go into the data folder and delete the XX folder; make sure you leave the EN folder alone.
Finally, get the AppCompactor from and compact the entire Periodic Table Viewer folder.

AFTER: 60.7 MB

I was going to ask what takes up all the space, but then I saw on the features page that it has 200 high res images, I guess that explains it.

Also, the features page says the uncompressed size is only 65MB. Which is it, 65MB or 120MB?

@Hydaral: I'm not sure what's up with the website; the app comes to 118 MB on my system. You can get it down to 60 MB, though, by following the instructions I posted above.

Incidentally, the images aren't the biggest space problem here; HTML pages are. When the Periodic Table Viewer is downloaded "as-is", there are 4,274 HTML files for a total filesize of 55.1 MB. That takes 46.5% of PTV's total size; images, by comparison, only take 39.8%.
After downsizing PTV as I described above, the 2,215 remaining HTML files still take up 45.4% of PTV's total size; images take up 48.3% at this point.
Unfortunately, there's nothing we can do about the HTML files; they appear to be used internally by PTV.

@ lautrepay: Thanks and updated.

Lastest uncompressed version 1.7.2 is 73.4 MB, Are you downloading the portable version?

Followed portablefreakers steps..
1) Deleted ADPT.exe and ADPT_Mini.exe.
2) There was no XX folder.
3) UPX'd "pt_explorer.exe" (I don't normally recommend using UPX due to AV conflicts.)

Before: 74.3 MB
After: 63.5 MB

@computerfreak, You CAN do something about HTML files..

It's called HTML Optimization! There's a tool called Absolute HTML Compressor (untested portable) that can shave off a couple MB's.

1) Go to options Uncheck "create backup"
2) Check "Compress files in a folder"
3) Select "pt_portable" or the main folder.
4) Press compress

Before: 63.5 MB
After: 54.2 MB

For images I use FastStone Photo Resizer:

For JPGs
1) Output format: jpg
2) Add folder: pt_portable\data\images
3) Settings: Set Quality slider to between 30 - 6003AHJ_VusJGXk1LbRSY_foMSop7yIlZ7_th_9ZlkppOpCf7vyIp2v4PxtJ9bkvADZq2dbUDB0ttHddmS407HtlseIOLSIOvp03AAOqGkmtITYuhMlGWYYvHe8hmeJUWzVeUI-SzeFQ-s_G
4) Output folder: same as input folder
5) Press convert

Before: 54.2 MB
After: 49.3 MB

Continue steps 1-5 for the different types of images ( not all of them listed here)

Output JPG
Quality slider to between 30 - 60

Output GIF
Compression 128 colors

Output BMP
Compression: RLE
Settings: 65536 Colors

Evenutally I got it down to 15 MB's by OCD compression of all the different types of images, sorry for the long post.

retroboy: please move all that to forums

With all due respect, "Emka" should have checked the link before posting an update...because both the website link and the download link lead to a 404 page. I might have been able to understand this if this post were several months or even weeks old, but this supposed update was posted only two days ago!


lautrepay 2011-12-26 19:59

@Bluestocking: And if the links weren't broken at the time that Emka updated the entry?
I can assure you that the DL link was not dead at the first days of december. I downloaded Periodic Table Explorer following the link given by WinPenPack website... and it's dead today.


Emka 2011-12-26 20:10

Sorry Bluestocking, I would not have come across the update if the link had been broken that day. I have no idea what happened there.


webfork 2011-12-26 23:26

Bluestocking: as a volunteer, Emka is not getting paid for his work here and we appreciate his efforts.


lautrepay 2011-12-28 02:55

Website is back and DL link is working again.


lautrepay 2011-12-28 03:31

By the way, Mr. Freshney changed his mind. The announcement of the link posted four comments above was modified. Now he says that he will continue whith the development of his software.
