What are he*.tmp files in %TEMP% folder?

[alex]

After the first start of the hippoedit you will find some new temporary files in the Current User temp folder created by the editor. In most cases these files are buffers for xml parsed data to speed up hippoedit next start. You can delete them or disable creation (if you want pure portable behavior) but this will result in slower startup.

Here are the description of all files:
heautocorr.tmp - pre-compiled auto correction data
hecolors.tmp - pre-compliled current color schema data
hegeneral.tmp - pre-complied general settings
hekeymap.tmp -  pre-compiled current keyboard mapping
heplugin.tmp - pre-complied list of found plug-ins dll
hesyntax.tmp - pre-compiled syntax files data
hefilepref.tmp - file with all file related settings. For example when you set encoding for file different from default or syntax, or word wrap for a some file, this is store here. So if this file will be deleted or lost, these settings will be lost. Paths to files are absolute.

If you for some reasons want to disable creation of these temporary files, you can start hippoedit with command line parameter --portable.

( Or use "<Portable>true</Portable>"  in "hippoedit.config". Read more at http://forum.hippoedit.com/?/topic,144.msg1313.html#msg1313)
