China DOS Union

OK, first of all, thank you all for your guidance. I don't know if any senior has made a summary of this aspect. If there is, this post will be regarded as a supplement, which can also guide rookies like me. The summary is as follows:

(The following commands run on NT systems)

1. fsutil (must be logged in as a member of the administrator or administrator group to use): (See floor 3)

For example: for /f "skip=1" %%i in ('wmic logicaldisk where "drivetype=3" get caption') do (
for /f "tokens=1,2 delims=:" %%a in ('fsutil fsinfo volumeinfo %%i\ ^| find "File System Name"') do echo %%i %%b
)

2. wmic (needs to be registered the first time used): (See floor 9)

For example: for /f "skip=1 tokens=1,2" %%i in ('"wmic logicaldisk get Caption,FileSystem"') do echo %%i %%j

3. chkntfs: (See floors 12, 20)

For example: for /f "skip=1" %%i in ('wmic logicaldisk where "drivetype=3" get caption') do (
for /f "tokens=1,2 delims= " %%a in ('chkntfs %%i ^|find "Type of File System"') do echo %%i %%b
)

4. Tools like md or cacls: (See floor 14)

Can judge FAT or NTFS file systems, but it seems unable to confirm whether it is FAT32 or FAT16 and others.

(The following commands run on DOS systems)

1. 00000055 33 32
First get the DBR, then see if the two bytes at offset 55 are 0x33 0x32

(The following commands require third-party tools)

1. omnifs (a tool attached in the Ghost enterprise version, the current version is v11.0.01502) (See floors 11, 16)

In addition, the GDISK mentioned by moderator gmy is known to be a hard disk partitioning tool. Can it judge the file system type? Brothers who have used it please explain. I dare not write it down before confirming it, for fear of misleading others. Please forgive me.

If there are other methods, please continue to leave a post.

If it is a system above XP, try this:
fsutil fsinfo volumeinfo c:\|find "File System Name"

Sorry, I interrupted your discussion about the fsutil command.

This command can determine whether it is a removable drive or a fixed drive. Does that mean it can be used to detect whether a mobile medium such as a USB flash drive is inserted?

Thanks everyone. The command mentioned in my above question refers to fsutil fsinfo

This fsutil fsinfo command needs to specify the drive, which is not very convenient. Using wmic is better.

Learned from the moderator:
@echo off
for /f "skip=1 tokens=1,2" %%i in ('"wmic logicaldisk get Caption,FileSystem"') do echo %%i %%j
pause

The simplest method:
@echo off
omnifs info >disk.txt
Open the text file disk.txt and it's clear at a glance!

Is this a method tool? Can you upload one?

Use md...\ to determine that FAT32 can be created, but NTFS cannot
