tmp
The tmp folder inside Adobe Acrobat’s macOS container stores temporary working files that Acrobat creates while opening, editing, exporting, or processing PDFs.
What is tmp?
~/Library/Containers/com.adobe.Acrobat.Pro/Data/tmp is a temporary-data folder used by Adobe Acrobat on macOS. Acrobat creates files here while it works on PDFs, such as during opening, editing, converting, printing, signing, or OCR-related tasks. Items in this folder are not your original documents; they are short-term working files that support the app while tasks are in progress. Temporary folders can grow over time, especially after large PDF jobs or interrupted sessions. Users usually encounter this folder only when checking storage or cleaning up Library data inside an app container.

Safety overview
Status: Mostly safe
This folder is associated with Adobe Acrobat’s sandbox container on macOS and stores temporary app data rather than primary user documents. Deleting its contents is usually low risk when Acrobat is fully quit, but doing so during an active PDF task can interrupt current work, remove unsaved temporary state, or force Acrobat to recreate files the next time it opens.
Recommendation: If you use Adobe Acrobat regularly, you can leave this folder alone and let the app manage it. If you need to free space, quit Acrobat first and then remove old temporary contents from this tmp folder. Expect Acrobat to recreate the folder automatically, and reopen the app afterward to confirm your current PDFs and workflows still behave normally.
