Skenovanie disku vidí názov a cestu úplne každého súboru a priečinka na vašom PC. To nie je niečo, čo by ste mali niekam posielať.
Skenovanie disku znamená čítanie kompletného zoznamu súborov a priečinkov na vašom počítači — názvy projektov, dokumentov, osobné štruktúry priečinkov. Disk Analyzer nič z toho nikam nenahráva ani neprenáša. Všetko sa číta a analyzuje lokálne a tam to aj zostáva.
Skenujte disky s miliónmi súborov za sekundy pomocou natívnych Windows API — žiadny upload, žiadne cloudové spracovanie, žiadne umelé limity veľkosti disku.
Disk Analyzer nepotrebuje na fungovanie žiadne pripojenie — skenujte a upratujte svoje úložisko kdekoľvek, aj úplne offline.
Yes — Disk Analyzer is completely free, forever. No Pro version, no payment, no sign-up required.
Very fast — the app scans in parallel and can handle even large drives (1 TB+) in seconds to a few minutes.
No — Disk Analyzer only reads and displays usage information. It never modifies or deletes any files.
