How to use SAPCAR?

Dear Experts,

I tried to use SAPCAR.exe to extract *.SAR files but somehow it appeared an error message, which it seems like it tried to extract from SAPCAR.exe file itself as well.

I tried many ways, such as follows:-

I pasted the sapcar.exe in the same directory where all the *.sar files located.

I used the following options.

sapcar -xvf *.sar

It extracted all the files in alphabetical order till the letter "s", which it also tried to extract from sapcar.exe. Therefore, the rest of the files, after "s" were not extracted.

I did try to use the following option too.

sapcar -xvf *.sar -R d:\patch file (I use the sapcar.exe from different directory than the directory where all *.sar files located).

But still not working, maybe I used the wrong switch.

Does anyone knows the right way of using SAPCAR?

regards,

Abraham
