CHK 1.02 - file analysis tool

[encode]

Okay new version is out!

Key features:

• SHA1 & CRC calculation
• Compression ratio estimation (Compression prognosis)

Enjoy!

I have two suggestions:
- make version for Linux
- make OpenCL-accelerated hash computation - Radeons excels at hashing,

[zody]

or maybe multithreading..would speed up the hole process a lot and the gui is still usable while adding files =)

I like this program There are some shortcomings though... CHK reads from my disk with only around 10 MB/s (one big file) and uses ~80% of one core, does it do both checksums from one disk read? When I copy that file on the same partition, explorer can do 50 MB/s disk traffic.
Feature request from me: Possibility to change column order, also probably different icon, this one doesn't seem as good as you usually do

EDIT: Clarifications

[encode]

It does all at one disk read - it read buffer and compute - SHA1, CRC and compression estimation at the same time. All that computations need some time - so it can't get full I/O speed.

[Black_Fox]

That's good to hear, however why isn't even one full core of quad-core used then?

[encode]

I guess due to memory access. The CRC/SHA1 need a small amount of memory, but my compression estimator uses about 18 MB which is randomly accessed (hash pointed).
