Can I delete the folder C:ProgramDataPackage Cache?

Solutons:


TL;DR: Do NOT delete this folder

(see below for workarounds)


Why Not?

There have been conflicting reports about whether the absence of this folder (as a consequence of deleting it) will actually and in all cases cause issues with the visual studio installation, i.e. during normal operation, during reinstall, patch/upgrade, repair install, or uninstall. However, the recommendation from MICROSOFT is clearly to NOT DELETE IT.

From Microsoft Developer Tools Blogs → HERE

When repairing, modifying, or uninstalling a product or when
installing or uninstalling a patch, if source media is required the
package cache is used automatically and most users will never see a
prompt. Only if the package cache is missing or incomplete will Visual
Studio setup prompt to download (if connected) or locate media as
shown in the screenshot below.

Visual Studio 2012 Prompt for Source

Users who have installed from media even get the option to download
(if connected). So while very few customers should ever see this
dialog, we wanted to make sure the experience was easy.
Even though we
will prompt to download packages to the cache if missing, we recommend
users do not remove the package cache. Not only is the cached used by
many other products that are installed with Burn and may not provide the same download experience, there are scenarios when
Windows Installer may require source that we cannot handle because our
code is not running.


#Solution/Work-Around:#
If you need to reclaim this space, your safest bet is to avoid “deleting” anything, but to instead, move this folder and all it’s files. You can safely do this following the instructions below to any local/live, online, near-line, or offline storage as long as that storage system that can be mounted to a drive letter or any mount point on the NTFS file system. Any of the following will work:

  • another live (mounted) partition
  • an optical disc (CD, DVD, etc.) with a live filesystem like FAT, or NTFS
  • an external hard drive
  • a USB drive
  • a network drive

Whenever you are prompted for the media/receive any errors about missing files/missing location, you simply make sure to remount/reinsert your drive/media if it’s not already a live partition.

Once moved, in order to “link” the old mount point/location (in most cases C:ProgramDataPackage Cache), you simply create a directory junction to it.

Junctions are recognized at the file system level as an alias entry in the FSTAB. Therefore, it’s transparent to all programs, including the OS itself. In other words, it is NOT seen as a file that simply points to another location (like a shortcut) and therefore always works without incident.

  1. You would move the folder(s) in question to its new location

  2. Create the junction

    • Option 1. (natively): Just issue the built-in Windows Vista / 7 / 8 command and the cmd prompt:

        mklink /J oldpath newpath
      

    NOTE: If you make the newpath absolute, you’ll be able to move link without breaking the pointer to the newpath. If you make the newpath relative, you’ll be able prevent breaking the link, as long as you move BOTH the link and target TOGETHER and maintain their relative paths.

    • Option 2. (using a tool): Another GREAT alternative is a free handy utility I’ve been using for years called “Link Shell Extension”. LSE is free and you can find it here (or Google for it): http://schinagl.priv.at/nt/hardlinkshellext/hardlinkshellext.html

      LSE allows you to create symlinks, hardlinks, junctions, smartcopies, smartclones, smart mirrors, smart moves, splices, multiple sources, and bunch of other stuff I found too confusing to read, frankly. But, it’s a brilliant free product that creates a Windows Explorer context menu that allows you right-click on your LINK-TARGET folder then drag it to where you’d like to create the actual link. You can of course rename the link to anything you’d like.

I’ve found the same folder on my laptop after installing VS2012. I tried renaming that folder to ‘__Package Cache’. When I then tried to uninstall VS2012 the uninstall process failed to start.

More information is available here.

For Visual Studio 2017, you can disable the package cache (even after Visual Studio is installed) by calling:

"%ProgramFiles(x86)%Microsoft Visual StudioInstallervs_installer.exe" --nocache

I gained about 2 GB of disk space on my system drive from that (YMMV).

For details, see the docs: Visual Studio Docs: Disable or Remove the Package Cache
