Storage and linked files

Reviewed October 2026

Every company gets 2 GB of file storage free. Instead of uploading, you can paste a link to a file or folder in Google Drive, OneDrive, Dropbox or any web link; links open from the project and use none of that storage.

It's free to run projects in ProtoPM.

What counts toward storage

  • Documents and photos you upload in a project's Files tab, and photos attached to field items.
  • A company's invoice logo and its public showcase logo.
  • Links do not count: only stored files do.
  • Files are kept exactly as you upload them. ProtoPM does not resize or compress photos.
  • Up to 25 MB per file and 20 files at a time. Photos (JPG, PNG, WebP, GIF, HEIC), PDF, Word, Excel, PowerPoint, CSV, text and email files (EML, MSG) are accepted.
  1. Open the project and go to the Files tab.
  2. Choose Add, then Paste link.
  3. Give the link a name and paste its address from Google Drive, OneDrive, Dropbox, SharePoint, a plan room or any web page.
  4. Choose Document or Photo, then Add link.
  5. The link appears in the Files list. Selecting it opens the file in a new tab.

Good to know about links

  • A link is a pasted address, not an integration. There is no sync, no file picker and no preview inside ProtoPM.
  • Who can open a link depends on that link's own sharing settings in Google Drive, OneDrive or Dropbox.
  • If the file is moved, deleted or unshared, the link stops working.
  • Viewers can open links in the Files tab. Guests do not see the Files tab.

If you need more storage

  • Storage packs are optional and billed per company: +25 GB is $5 CAD/mo and +100 GB is $12 CAD/mo, and they stack. Nobody pays per user.
  • When a company is full, new uploads are declined until space is freed or storage is added. Adding a link still works.
  • If a storage add-on ends and the files no longer fit, the company gets a 60-day grace period with reminder emails before the largest files are removed to fit. Projects and records are never deleted.

Common questions

How much storage does ProtoPM include?
2 GB per company on the free plan, enough for hundreds of full-size site photos plus documents. No credit card.
Can I use Google Drive or OneDrive with ProtoPM?
Yes, as links. Instead of uploading, paste a link to a file or folder in Google Drive, OneDrive, Dropbox or any web link; it opens from the project and uses none of your storage. Who can open it depends on the link's own sharing settings.
Do linked files use my storage?
No. Only files you upload count toward the company's storage.
Does ProtoPM compress my photos?
No. Photos and documents are stored exactly as you upload them.
