Dumping Apple floppies ?

Finally decided to tackle my 30 or so Apple Floppies.
These are either genuine originals or made on or for Apple I or II ..
I have no idea what settings to use here ..
The DOS used is likely to be 3.2 but really I have no idea ..just guessing ..
So what format to dump in .?
again no idea .
Is there an emu output I can choose ..like .D64 for the commodore ?
That way I can check dumped disk content on a PC
I tried my first one
MECC Computer Inspector (Genuine disk)
and used stream dump which appears to produce all green sectors on the GUI ..
but I have no way to check what has actually been dumped ?
can someone please advise.
and keep in mind I'm still a newb here and use the GUI

Any random batch of Apple II floppy disks are more likely to be in Apple DOS 3.3 format with perhaps a few Apple DOS 3.2 sprinkled in. I'd default to 3.3 and if that does not work then try DOS 3.2. The Kryoflux GUI will save to an image file that can be used in emulators.

Keep in mind that most commercial titles are copy protected and therefore may not decode properly, and will not run in an emulator unless an unprotected is applied.

The kryoflux will let you dump the first side of an Apple II floppy disk, however be aware that to read the back side of a "flippy" disk that does not have a second index hole, you must use a special "flippy modded" floppy drive.

The main issue with early protected Apple software is the same as was with Commodore 64 some years ago - all the custom formats need to be documented so a procedure to verify the data can be made.

Well ..
all I can do for now is wait until the drive I ordered arrives ..which hopefully I can mod as a flippy.
Then maybe I can dump these disks correctly.
we shall see.

Vipersan, I've done over 100 Apple II disk images, single and double-sided flippies, mostly DOS3.3 using this command structure for single-sided:

dtc -f(diskname here).raw -i0 -f(diskname here).img -x0 -i8 -l8 -dd1 > (diskname here).txt

Note: parenthesis are not included

So..I used the dtc command switches you posted airnocker and dumped 10 disks so far ..
some have shown errors as they dumped but most went smoothly,
I noticed the dump included Raw ..text..and .IMG ...
The .img file had size but nothing intelligable when opened with winimage.
Is there any utility that can make it possible to see the content of the dump ?
I guess what I'm asking is to be able to 'decode' content ..
Some disks are genuine (original) ..some are not ...thus content on those is unknown.

Winimage only knows about MS-DOS disks. There might be some utilities for Apple II Applesoft Dos/Prodos/Pascal disks but since there were so many oddball formats, the best way to be absolutely sure is to load them in an Apple II emulator. Bootable disks should start right up. Non-bootable Applesoft DOS/Prodos disk contents can be viewed with Copy II Plus in such an emulator.

Rather than go to the trouble of getting an emulator installed ..I wrote the dumped raw images back to empty floppies with wildewutz and tried them one at a time in my AppleIIe ..
of the 10 I dumped not one booted ..
so I guess I messed up either with the dumping process ..or the write back process..
I guess I still have much to learn.
For now I have simply cloned the disks with 'fast copy' on my IIe ...again to buy some time.
fwiw the 10 disks I tried were genuine AppleII and the clones are working fine.
