Determine whether Premiere Pro’s Project Recovery dialog reliably presents the most recent auto‑save (.prproj) file created immediately before a failed software upgrade.
The upgrade process may lock or temporarily rename the project file, potentially interfering with the auto‑save mechanism that writes to the same location. Because the documentation does not guarantee which version appears in the recovery dialog, it is unclear which factors—such as auto‑save interval, folder location, or the timing of the file lock—control the selection.
Which auto‑save file does the recovery dialog select when the upgrade interferes with the project file? Does using a local auto‑save folder or disabling the upgrade’s file lock improve reliability? Is there a preference or workflow that forces Premiere Pro to recover the latest auto‑save?

The Premiere Pro Project Recovery dialog selects an auto-save file based on the modification timestamp of .prproj auto-save files present at the moment the crash dialog opens. When a failed software upgrade locks or renames the project file, the auto-save mechanism may be unable to overwrite it, causing the recovery dialog to present an older version or no recent auto-save at all.
Likely explanation: If the upgrade lock prevents the auto-save thread from writing to the project file location, the save may be skipped or a new auto-save file may be generated with a higher sequence number in the configured auto-save folder. Whether that newer file appears in the recovery dialog depends on if it was fully written before the crash and if its timestamp is the most recent at that moment.
Research brief observations: The research brief notes that auto-save interval (default 5-15 minutes) and the timing of the upgrade relative to the last save determine whether a recent auto-save exists when the recovery dialog opens. It also notes that using a dedicated local auto-save folder on the same drive as the project reduces the chance that a remote or locked folder blocks the write. However, Adobe does not publish a preference or command that forces the recovery dialog to prefer the newest auto-save, and behavior may vary between Premiere Pro CC 2024, 2025, and earlier versions.
Practical verification: Locate the auto-save folder path in Premiere Pro Preferences Media Auto-Save Location and compare the timestamps of the .prproj auto-save# files with the project file's modification time. After a simulated upgrade lock, observe whether a new auto-save file appears and whether it is listed in the Project Recovery dialog.
Missing diagnostic detail: Which Premiere Pro version are you running (CC 2024, 2025, or earlier), and does the project reside on a local drive, network share, or cloud-synced folder? This information determines whether the folder-location adjustment applies.
