Hi,
The metadata extraction of GIF & BMP images have some problem as described below:

I have tried both the ways to extract embeded metadata from above image files using linux os and windows os. The metadata field "File Creation Date/Time" returns a valid value in windows (exiftool.exe) but the same image file doesnot return "File Creation Date/Time" value in linux(exiftool.sh). The extraction is made on command prompt both in windows and linux.

Let me know what is the problem.

Hi Chandra,

See the Extra tags documentation for a description of this tag.

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

Hi Chandra,

The ExifTool tag named FileCreateDate is not metadata in the file itself.  This information is stored in the filesystem.  Windows and Mac filesystems store this information, but Unix filesystems do not.  Currently ExifTool can only read this from Windows filesystems.
