Multi-Client utility

enneract · #1 11-25-2010, 07:40 PM

I generally play on my laptop with a 64gb SSD, so disk space is at a premium. I also like to play on a couple different servers with different client requirements. As such, I created a small utility which can recursively symlink the files in a directory (not create 'directory junctions'), so that server-specific changes can be made, using a minimum amount of disk space (at most a few MB, instead of 4GB per client install).

For those not in the know, a symlink basically makes your computer think that a single file (stored in a specific space in physical memory), exists in multiple places in logical memory simultaneously. So, if symlinked, C:\Foo.txt and C:\Bar.txt have the same contents, and if you edit Foo.txt, Bar.txt will also be changed. The other consequence is that only 1 file's worth of storage is consumed.

Cleaned it up, here it is.

Command line, usage is

Code:

EQEClone -s <source> -d <destination>

Run the app, it will create the new folder, and symlink the contents. It will create a COPY of eqhosts.txt so that you can use a different login server. Copy over any server-specific alterations you might need, overwriting whatever. Note that EDITING any file that you havent overwritten in the clone folder will also CHANGE THE SOURCE FOLDER'S COPY. Renaming, deleting, etc, will not, though. I don't know what you'd edit besides eqhosts.txt, but keep it in mind.

Your antivirus might not like it due to being a packaged autoit macro. It isn't a virus.

source, for the paranoid for the above reason:

Code:

; Creates symlinked EQ:Titanium install for Project1999

Nice! I've been looking for something like this.

Does this work with Windows 7? Can this be used on Live installs? So I can have a LiveEQ, TestEQ, and BetaEQ folder, with just the changed contents?

It probably ONLY works on windows 7. It might work on Vista too, but not sure.

As for working on live installs... Maybe? I don't know, I haven't tested it. The patcher may or may not bork the original install.
