date time stamp in files

Hello,

Check your file watcher settings in Settings | Tools | File Watchers - must be some placeholders in file names.

Tnx for comment but i didn't set any filewatchers in PhpStorm i checked and the screen is empty

What OS you are using? If its Windows ... you may use something like Process Monitor and see what process creates them and that may give you some hints. IDE by default does not create any of such files.

BTW -- what kind of content that file has?

When does it happen? Maybe it's related to web page debugging?

He does it with a files when i'm programming for drupal.
Less files, tpl.php files even de info file for  module
Less it self is generated at server site.
I put into the settings that the file has to be saved at CTRL-S

I can try process monitor
Tnx so far.

Less is a preprocessor for CSS -- http://lesscss.org/ ... so .less file should contain CSS. Usually such files should not be generated on the fly .. especially considering the file names given (with timestamps).

I'm not Drupal user or developer ... so don't know what else might be stored in such files. Especially if they are auto-generated...

Sorry, do not understand what you are trying to say here...

But see what you can make out of such files content.
