Organise COME installer files after first use
Once the app opens and account access is clear, review saved installer files individually. Keep cleanup separate from app and account management.
Identify useful records
Keep a note of the source and installed version if it helps future troubleshooting. A file's saved date is not its release date, and a duplicate-name suffix does not identify the version.
Review redundant copies
You can decide whether older installer files are still needed after checking their identity and location. Do not select unrelated downloads or assume that deleting an APK uninstalls the app. Read file-manager confirmations.
Avoid keeping confusion
Several unexplained files can make a later update harder to assess. Retain only what you understand, and obtain future updates through a current traceable route. Do not treat an old local copy as permanently current.
A useful next step
Use Android's app entry for normal use and return to the download guide when a future file task arises.
