FileTimes

Java class library to get/set file and directory times: Create/LastModified/LastAccessed. For Windows only.

Create time is when the file was first written. Modified

time (sometimes called lastModified) is when the file was

last written. Accessed time is when the file was last read

or written. Checking its date, looking at its attributes or

checking to see if it exists does not count as reading it.

Get/Set Windows File Times Create/LastAccessed/LastModified

with a JNI native code class.

Java and JNI you include in your own code.

You can test with

C:

CD \com.mindprod.filetimes

java com.mindprod.filetimes.FileTimes

and ensuring filetimes.32.dll and filetimes.64.dll are on the path, e.g. in the

current directory.

See FileTimes.java for the API to use these methods in your

own programs. FileTimes does nothing by itself, other than a

debugging test harness to demonstrate the methods.

Windows keeps file timestamps accurate to 100 nanoseconds

with 10, 000 times as much precision as Java's 1 ms. This

means if you copy a file in Java, the new file will not

have the exact same timestamp as the old. This package

retrieves and sets timestamps accurate only to the

millisecond.
