How to delete files end with a substring and older than N days

问题

I want to delete extensionless files older than 7 days whose names end with _C.

Example files:

B_C_A1_C
B_C_A2_C
B_C_A3_A
test.txt 

My code:

SET mypath=%cd%\downloads
ForFiles /p %mypath% /d -7 /c "cmd /c del /q %mypath%\*_C

When I execute the code, it deletes all files which contains _C, but I want to delete only files which end with _C and are older than 7 days.

How can I fix this?

回答1:

For more information about the forfiles documention, see Batch file to delete files older than N days.

The wildcard expression *_C selects any files which end with _C, regardless of whether it has an extension.

The final code is insanely complicated:

forfiles /p "%cd%" /m *_C /C "cmd /c \"echo @file^|find \".\" ^|^| del @path\""

Using *_C will select the following:

anything without periods_C

It will NOT select the following:

any.thing_C
anything.txt._C
anything containing periods_C
