What are: "Update.strings" documents?

Question

I have several items that appear to be blank documents in my web receipts folder. Here is a list of some of them:
Update.strings
Update.strings 07-37-37
Update.strings 07-37-37 2
WelcomeSetupExtensions.strings
WelcomeSetupExtensions.strings 07-37-09
WelcomeUpgrade.strings
What are these and can I trash them? If not, can I move them someplace other than my web receipts folder? I keep all online purchase receipts in my web receipts folder and I don't want to muddy the waters by having other such items in that folder.
Thanks in advance.

update function modules are used whe u want to perform the updates all at once. for e.g u have a sequence of screens on which user will enter data. on each screen if u save the data directly to a table then if there is some problem before completing the transaction, system will have incomplete and inconsistent data.
for this  u will use
call function 'FUNCTION_MODULE_NAME' in UPDATE TASK.
and pass it the data.
when u will trigger the COMMIT WORK command system will execute all the function modules with UPDATE TASK and update the database then only,
