when you write to km, just give it a new name.

i don't see there is any issue.

Hi,

You cant store the same file, into the same folder path, more than once in KM.

KM has the concept of RID(Resource ID), which is defined by the file path. For example if you store a file named File1.txt under say documents folder, then the RID of the file will be /documents/File1.txt. And since RID should be unique, It will not allow you to store any other file (or the same file) with the same name into the same folder path.

Alternate solution will be to append the file name with the current system time stamp or different index every time you upload the file.

Dear Vishwa,

It is a very useful answer please guide me to add timestamp to the file or to add index .

Hi,

You can use the below snippet to append time stamp.

int positonOfDot = fileName.lastIndexOf(".");
String fileExtn = "";
String fileName_withoutExtn = "";
String timestamp = "";
Date currentDate = new Date();
SimpleDateFormat sysTimeStamp = new SimpleDateFormat("yyyyMMddHHmmss");
timestamp = sysTimeStamp.format(currentDate);
if(-1 != positonOfDot){
fileExtn = fileName.substring(positonOfDot + 1);
fileName_withoutExtn = fileName.substring(0, positonOfDot);
fileName = fileName_withoutExtn + "_" + timestamp + "." + fileExtn;
}

Where fileName is the String variable holding the name of the file.

Hi,

Appending index to filename, i ment append "(1)" to the existing file name, instead of timestamp as shown below

fileName = fileName_withoutExtn + "(1)." + fileExtn;

But appending timestamp would be a better approch.
