Hi, I have a question about UltraEdit's forced interval file change detection. I have a local file which is modified frequently by several remote computers. Under the File Change Detection heading in the configuration menu, I have set automatic updating of changed files and a forced poll interval of one second. Then I turned on File Change Polling for the file in question. It works well, but my question is whether the one second interval is too low. I know the file is only reloaded in the editor if a change is detected, but how is that detection done? I'm assuming it is left up to the operating/file system to mark the file as changed, rather than UltraEdit constantly reloading the file to check. Does anyone know if the file is only read from disk if there was a change detected? I just want to make sure the file isn't read from disk over and over again every second.

Thanks in advance.

I'd say you'd have to mail IDM and ask, because only they know how they've implemented that.

I guess you could check the access time on the file and compare it to modify time ie. something like this:
Notice the "Access:" info in both cases.

That of course requires you to have something to check that with, dunno what's available under windoze except for properties which probably is too slow to play around with for your test. I'm sure there's some program to try with tho^^

All I wanted to know was whether it's safe to leave the poll interval at such a low value. Just wanted to make sure my hard disk isn't accessed thousands of times unnecessarily each day. Thanks for your replies, much appreciated.
