DISM: The system cannot find the file specified when the file exists.

I used the following lines in a CMD script:

Code:

If exist "D:\CAB\WinPE-FontSupport-ZH-TW.cab" (echo The font file exists. >> "%Log%")
If exist "D:\CAB\lp.cab" (echo The lp file exists. >> "%Log%")

DISM /image:%X% /add-package /packagepath:"D:\CAB\WinPE-FontSupport-ZH-TW.cab" /LogPath="%Log%"
DISM /image:%X% /add-package /packagepath:"D:\CAB\lp.cab" /LogPath="%Log%"

According to the "%Log%" file, the two .cab files actually existed. However, I have got the following errors:

Code:

An error occurred trying to open - D:\CAB\WinPE-FontSupport-ZH-TW.cab Error: 0x80070002  

Error: 2  

The system cannot find the file specified.  

The DISM log file can be found at D:\Windows PE\WinPE_log.log  

Deployment Image Servicing and Management tool  
Version: 10.0.18362.1  

Image Version: 10.0.18362.30  

An error occurred trying to open - D:\CAB\lp.cab Error: 0x80070002   

Error: 2  

The system cannot find the file specified.

Why couldn't the system find the files, which definitely existed?
"WinPE_log.log" gives the following info:

Code:

When I manually run the following via Command Prompt, the .cab files will be opened.
D:\CAB\WinPE-FontSupport-ZH-TW.cab
D:\CAB\lp.cab

Command Prompt can find the two .cab files as shown below:

Code:

C:\Windows\system32>Dir /a "D:\CAB"
 Volume in drive D is Data
 Volume Serial Number is 0D22-074F

 Directory of D:\CAB

Might mean DISM can't process that particular file... an educated guess based on the limited education provided by reading this:
