Read Files Tech v2.15.1
The Android Swiss army knife for your files: file explorer, universal reader, scanner, OCR, vault.
Security audit — May 2026ℹ️ At install time
Read Files Tech is distributed outside the Play Store (sideload). The combination
MANAGE_EXTERNAL_STORAGE + REQUEST_INSTALL_PACKAGES — required
for the universal file explorer feature and APK install from the explorer —
was long flagged by Google Play Protect as a dropper signature.
That is no longer the case: the app was submitted to Google's review and
passed it. Installing no longer requires any special step.
There is therefore no reason to disable Play Protect — leave it on. The app remains fully open source (Apache 2.0), signed, and scanned by VirusTotal. Read Files Tech never downloads nor installs an APK in the background: every install goes through the system PackageInstaller with your explicit consent.
