CHK files

Microsoft Windows 98

I just resized (increased) two of three hard drive partitions, one of them
being C drive, using Partition Magic. Everything went OK, although I had to
run Scandisk, which did find and correct errors, after the first attempt at
resizing C. This per the program's error message instructions.

After C:\ I now show thirty two .CHK files at 4096kb each and three .CHK
files at about 35,500kb each. I don't know if these were created by Partiton
Magic or Scandisk, but in any case, is it safe to delete them?
They are sectors that scandisk could figure out what to do with. They
weren't linked to any files, but they didn't belong to the "available
space" chain either. You could try looking at them with a text editor
to see if there's anything you are interested in, but you aren't
likely to find anything. Go ahead and delete them.
The 4096 kb's don't seem to amount to much anddeleted them. The three 35500
kb's are executables. OK to delete?
I thought you said they were CHK files ? how did you determine they were
EXE's ?
They are CHK files, but as Tim suggested I looked at them with Quick View
Plus.
<SNIP>

ahh so you saw raw data and not text ...it should be fine to delete them. as
i stated previously ..I had my scandisk set to free up the files and not
even create the CHK files :>
where there is Binary data, delete those chains & remember they existed
there is a very small chance that they are from a necessary executable that
will turn up corrupted,
If an executable turns up in the future unnaccountably altered and your AV &
spyscanner shows no problems
Dont panic, you havent been hit with a new super bug, you just have the tail
of this problem

Rule #1: Snow before Windows. Now that that's taken care of....

Here is the start of the innards of those three files:

WINDOWS EXECUTABLE
32bit for Windows 95 and Windows NT

Technical File Information:

Blah, blah, yudda, yudda...


I think I know what these files are about. In the lines above there is the
line "Magic: 010b". Because (in this case) ScanDisk needed to be run first
but wasn't, there were a couple of instances where Partition Magic couldn't
get through its DOS procedure. But it saved what it had done, because after
ScanDisk was run, the program raced through its original work in DOS and
finished up at the normal plodding speed. I uninstalled Partition Magic
after I was done, so if there were any lingering consequences, they should
be gone now. Anyway, I'm all shovelled out, so in case I'm wrong the route
to BestBuy is free and clear.

Such as you quoted are usually setup.exe files or simlar. They may have
been critical update source files, or whatever.

If the PC is running okay as these are "chk" files now, don't sweat the
load.

Scandisk and defrag should be run prior to any partition change with PM, or
imaging with an imaging program.
Nope.....the Magic:010b has nothing to do with Partition Magic. It is a "magic
number" included in the file type.

Glen, when I clicked on that link, Wikipedia stated that it did not have
such an article, inviting me to begin ...?

Thanks for your response, Hugh. Glenn's answer told me what I needed to
know--that I didn't look closely enough at what I was doing!

That is because the closing parenthesis in the link is missing. If you look closely
at the link in my message, the word "programming" is in parentheses, like this:
(programming) but the closing parenthesis is not included as part of the clickable
text (it isn't blue, or whatever color your browser uses for links).
http://en.wikipedia.org/wiki/Magic_number_(programming)

When you click it, you will actually be clicking:
http://en.wikipedia.org/wiki/Magic_number_(programming

You must either copy and paste the entire link including the last parenthesis, into
the browser address bar, or click the broken link and then manually add the ) to the
address bar after the page comes up saying they don't have that article.
Thanks, Glen. Even though I hate being unobservant like that, I really
appreciate your feedback. :-)

One thing I hate about computer programs is that sometimes when things ought
to be coldly analytical they go "humorous" on you, to wit "Magic: 010b";
other times a little lightening up wouldn't hurt, like in manuals, back when
they had them. Not that I haven't made these same mistakes on this board
from time to time.

You may be aware that there is a file on your computer named webshlock
(literally, "webjunk"). I say this because you had mentioned you use Avast,
as I do, and Avast puts this self-replicating-upon-deletion bastard there in
my Temp folder, where it seems never to have any content whatsoever but
manages to change its date daily. If ever there was a file made out to
appear like spyware to the toiling masses this was it, and I was Googling
around and searching Trend-Micro trying to figure out how to get rid of this
thing, and wondering how many hours out of my life THIS one was going to
cost me (about 2). Ha ha ha.
D'oh!
(but I might still be correct, only now with no "proof")
scandisk has the option to create these files or free the space....

as Tim says , *usually* it is fine to delete them (i had mine set to free
the lost segments ..therefore never creating CHK files)
