Bug in Adobe Creative Cloud update deletes Mac user data

Here’s a major warning to those of you who use Adobe Creative Cloud on a Mac: the latest version of Creative Cloud has a bug that deletes unrelated data from your root directory without warning.

The bug in Adobe Creative Cloud version 3.5.0.206 was discovered by the cloud backup service Backblaze, whose customers were having their data deleted by Adobe’s app.

Here’s what’s going on: Creative Cloud appears to be deleting the contents of the 1st folder in your Mac’s root directory, in alphabetical order. For Backblaze customers, this folder was often the Backblaze directory called .bzvol. If you have a different folder that comes earlier alphabetically, something like .appdata, for example, then that folder will be affected.
