The Pogoplug http://my.pogoplug.com/share/ website is so smart that if you share

an .xls file it can show you (with preview, the magnifying glass with the + in it)

what the spreadsheet inside that file looks like.

Yet, the pogoplug website is so stupid that it shows it as an image... meaning

you cannot copy/paste any of the cells of  your spreadsheet!

Same with a .txt file.

I thought surely they must have a LIST of what extensions the website previews

and how it treats them.  But when I asked, they said no, they had no such list!

Am I the only one interested?  Here is what I have so far:

Ext    Preview shows..

.jpg     Image

.txt     Image that looks like text (cannot copy/ paste lines or fields)

.xls     Image that looks like spreadsheet (cannot copy/paste contents of individual cells)

.htm   Image (links are highlighted in blue...but you cannot click

           on them since the whole page is one image)

.bin    [no preview offered] (can’t really complain about this I suppose)

.exe    [no preview offered] (ditto)

On the .txt and .htm files, I keep asking myself what is the point of

 converting them to an image?  Isn’t this actually more work than

serving them as plain text?  Is it just laziness, or is there some

SINGULAR SINISTER ATTITUDE OF MIND that motivates this

behavior?  May I have a clue please?

(And I know that I can “always” download the whole file and then open it on

 my PC if I want to pick out a cell or click on a link or whatever).

Thanks!
