CIRCUMSTANCES: Update 0.984 (Work Drive, Project Space)
SIZE: ~4.6 MB


Across the past releases, we've shared our intention to tackle the P drive concept (including all the scripts used to maintain it). To deliver on this, we introduced Work Drive late last year, which has been updated over the past month and it is now the only tool to prepare and maintain the Project Directory. All previously used batch scripts are now simply calling Work Drive with the appropriate parameters.

Speaking of the Project Directory (Drive); it's a new term to designate something most of you know: it’s the substitute drive P known as "P Drive". As explained in a previous personal blog, the P drive is a concept. In short, it’s the file structure for the game from the game's perspective, P being its root directory. To give an example, the file data_f_mark.pbo is physically located in \Mark\Addons in the file tree. However, once loaded, the game will set its mounting point to \A3\data_f_mark, which corresponds to the prefix of the PBO file. To sum up, P:\ is a representation of the working directory of the game, from the perspective of the game.

Like previously mentioned (in various places like the forums or older TECHREPs), Work Drive is a tool designed to replace the previously scripted systems in order to provide a more reliable way to manage the work drive (P) and its content. Its first iteration was only able to manage the well-known P drive and to install Buldozer. It did this from any location (source / destination). In the recent development updates, the tool received more abilities:

  • Mount and Dismount any substitute drive (mapDisk)
  • Maintain Buldozer (DevP)
  • Extract game data to any Project Directory (FuturaToP)
  • Create the symbolic links (mapFolders)

An important note is that Work Drive will select the main install of the game as source. The destination directory will be the same as your project space b y default , as defined from the launcher of the tools ( Preferences->Settings - CTRL+E). However, unlike the previous behavior (using the install directory of the tools), if no custom directory is defined, a default one will be used in the document folder of the current user (...\Documents\Arma 3 Projects). This is done in order to avoid any potential conflict with the updates of the tools.

A few facts about Work Drive:

  • It takes around 4 minutes to extract the game data from and to a SSD (~12 minutes with a HDD).
  • Work Drive runs multiple tasks in parallel.
  • The faster your hard drive, the faster the process will be.
  • In case of an update of the game, it takes usually between 1 and 2 minutes to update the extracted data.
  • Work Drive won’t update a folder which already is up to date.

In the upcoming updates, this new default environment will be adjusted and polished. Your user feedback is valuable - if you have any feedback, please come and share it in this forum topic.

Besides the above, some other tools have been updated. There isn't anything major to report on, only small adjustments that can be consulted in the change log below. In the event you would like to share your feedback or report an issue, the forums and the Feedback Tracker are at your disposal.
