Google's Free up space on your Chromebook article shows where the space went: select the time, then Settings, then under System preferences open Storage management, which splits usage into Downloads, Offline files, Browsing data, Android storage and Other users. Google says a Chromebook that is nearly full shows Device is low on space: Free up space or select data may be automatically deleted, and that downloads, page loads, settings changes, new accounts and Android apps can all fail before that point.
Its fixes are to delete files you do not need, move files to Google Drive, clear your browsing data and download history, uninstall apps you do not use, and remove extra user accounts. The base Chromebook Plus 514 has a 128GB UFS 3.1 drive per ITPro, and that drive is not a part you can swap at home, so freeing space is the repair.

Model-specific
What is true of this model and not of its siblings

- A 128GB UFS 3.1 drive on the base 2025 model per ITPro, with the Intel CB514-4H also offering a built-in MicroSD card reader per Acer.
- Repair cost
- Freeing space costs nothing. A failed drive is a board-level repair, typically $99 to $299 at an independent shop with a free diagnostic per BadgerLayer; the battery is a separate part, KT.00305.014 at about $56.87.
Stop boundary
When this stops being a self-service repair
- !If Storage management shows almost nothing used and the Chromebook still says it is full, contact Acer Support with the model number
- !If files vanish or the drive reports errors, back up what remains and book service, because a failing drive cannot be swapped at home
- !If the Chromebook is managed by a school or employer, the administrator may control storage and offline files

Exact questions
Common questions
Why does the Chromebook say it is full when I have few files?+
Storage management counts Android storage, Offline files, Browsing data and Other users as well as Downloads. Open it and read each block.
How much storage does the Plus 514 have?+
ITPro reports a base 128GB UFS 3.1 drive on the 2025 model, and Acer describes the Plus line as double the storage of the standard Chromebook.
Can I add storage?+
The Plus 514 has a built-in MicroSD card reader on the CB514-4H per Acer, which holds files but not apps. The internal drive cannot be swapped at home.
Does deleting Downloads free space at once?+
Yes, and it is permanent. Files in Google Drive stay online unless you pinned them for offline use.
What happens if I ignore the low-space warning?+
Google says selected data may be automatically deleted, and downloads, web pages, settings changes and Android apps can fail.
Will a factory reset free space?+
It removes local data and apps, and it erases everything stored only on the Chromebook, so back up first.
Why is Other users so large?+
Each account on the Chromebook keeps its own files, cache and Android data. Remove accounts nobody uses, as Google says.
