@Shades:
You may well be right in that WinRAR may have the "better" interface (e.g., You can browse and manage archives quite easily with it, and it seems quite intuitive), but this would depend on the subjective judgement from the personal (user) perception.
However, on your other point, it seems to me that the differential between the "absolute best" compression ratios and/or processing times between compression products might not be all that significant nowadays, given technology/efficiency advances, including, for example:

• adding hundreds of Gigabytes of extra disk storage comes at virtually little or no extra marginal cost;
• hard drive (disk) access times (read/write) are continually being increased;
• CPU cycle frequencies (speed or cycles per second) - in serial and/or parallel processing schemes - seem to be continuing to go up at an impressive rate with each new CPU brought out by the chipmakers - again at little or no extra marginal cost;
• the move to 64-bit technology and associated higher bandwidth bus sizes contributing to increased throughput and reduced access/fetch times in RAM/CPUs;
• RAM cycle frequencies (speed) continuing to increase;

Thankyou for the link to http://www.maximumcompression.com
Good knowledge content!     :Thmbsup:

To add to that link, there are a couple of general and related links which were provided by others in the discussion thread above, which I repeat below for our convenience and to put them together here with your link. They too have good knowledge content:
Wikipedia - Comparison of file managers

@mouser:

"See this thread and the sample URL virtual folder in CHS: http://www.donationcoder....um/index.php?topic=4135.0"

Many thanks! I took a look at that and then played about with the virtual folders using that SQL.
Results:

• All clips with URLs were filtered OK using the rule: (Lower(ClipText) LIKE '%http:%') OR (Lower(ClipText) LIKE '%www.%') OR (Lower(ClipText) LIKE '%ftp:%')
• All clips with "the" in the text filtered OK using the rule: (Lower(ClipText) LIKE '%the%')
• Text filtering failed using a rule with an upper case character as the first character in the filter string- e.g., (Lower(ClipText) LIKE '%The%') - so it looks as though the syntax is upper-case-averse.   :tellme:  (?)

Is there somewhere you can point me to to bone up on the subject of SQL commands and syntax for CHS?

On a side issue: What is the best way to sort/reorder the virtual folders? I can't seem to get them to behave nicely at all by moving them around.

Sorry if some of this is irrelevant to this discussion thread.

@rjbull:
Thankyou.

* Categorise/Organise your clips. Create rules/filters for incoming clips.
* Quickly access the source web page of internet clips.

It looks like the first item is therefore already in CHS - and is exactly what I had been looking for but didn't know how to do until mouser pointed it out.
The second item (i.e., retaining the reference of the source URL) would be very useful. That's the sort of thing that I notice OneNote does, but it only does it for copy/paste of text and/images from a web page. If you copy the same section of that web page as a OneNote image clip (using the clipping tool crosshairs), then it loses the source URL.

Har-de-har. Very punny. You get a C+ for that one.      ;)
