# How to upgrade Arachne

There is currently no user friendly way to upgrade Arachne WWW browser. You are strongly recommended to install new release of Arachne always to new directory, keeping your old installation as your back-up copy. If you need to save disk space, try to

- delete all files in old Arachne's CACHE subdirectory.
- use some archive utility (ZIP, ARJ, RAR, etc.) to pack files in old Arachne's directory. After unpacking, your backup copy of Arachne should work again.

Generally you can try to copy files with extension .cfg from your previous installation to the new one, but be careful with file mime.cfg, as new one can describe DGI applications required by the new installation of Arachne. Good idea is to reinstall all APM packages when upgrading Arachne - they will update new MIME.CFG automaticaly. You would probably also like to use your old bookmarks - hotlist.htm file. Files in MAIL subdirectory can be simply moved to the new mail directory, or you can use common mail directory for all installations of Arachne on youe PC (something like c:\mail\)

If you have decided to overwrite your existing application using Arachne self-extracting installator, you will find your old .cfg files and hotlist in subdirectory of Arachne installation directory called backup\.

# NEW!

Format of mail directory was changed in 1.45 beta: Received messages (*.MES files) are now stored in subfolders of your mail directory. It means you have to create new directory (call it let's say OLD\) in you current mail subdirectory, and copy all *.MES files to this subdirectory. Keep *.CNM, *.TBS and *.SNT files directly in mail directory.
