Using %.% in make file

I want to perform operations on a file inside the folder. There are 1000 folders and inside each folder there is one such file on which I have to perform some actions. Can I use the following? If not suggest me some method.

$(obj)/%.log : $(PATH)/%./%.c

No. GNU make only supports a single percent sign per target or prerequisite. Any percents after the first are treated as literal % characters.

You can use secondary expansion for this:

.SECONDEXPANSION:
$(obj)/%.log : $(PATH)/$$*./$$*.c
        run my command
