How can I get the directory(or folder) name?

[euihyun.jung@nokia.com]

Hello. I want to get directory name using Labwindows CVI. For example, my 😧 drive has 'aaa', 'bbb', 'ccc' directory(or folder),
and I want to get the directory name in specific folder using some function? Is there any function knowing the dirctory name?

Hello,
Please take a look at the function named "GetDir". This function gets the current working directory.

Also, the function "GetProjectDir" function gives you the directory in which the current project is present.

You may go to LabWindows/CVI help and search for all the functions related to dir or folder and see which one suits you the most.

Old question, but still relevant. 

I have the same question, but have not found the solution. E.g. when connecting an USB memory stick it will appear with a name, often when new, brand name of the USB memory. I want to look for a specific name.

I can’t find this with GetDir() 

Regards,

Gerhard

I'm not sure if you can get this information using a CVI library function, but you can certainly use the Windows API function GetVolumeInformation().

Yes !

Thanks,  it worked !
