Prečo offline

Prečo premenovávať súbory offline?

Hromadné premenovanie sa dotkne každého súboru v priečinku. Nemalo by kvôli tomu opustiť váš počítač.

🔒

Vaše súbory nikdy neopustia váš počítač

Hromadné premenovanie znamená, že appka má prístup ku každému súboru v priečinku — to nie je niečo, čo by sa malo niekam nahrávať. File Renamer pracuje výhradne na vašom počítači, náhľad aj aplikáciu zmien robí bez pripojenia k sieti.

⚡

Žiadne limity, žiadna fronta na serveri

Premenujte tisíce súborov naprieč vnorenými podpriečinkami za sekundy. Keďže všetko beží lokálne, žiadny upload, žiadny limit počtu súborov a žiadne čakanie v rade za inými používateľmi.

📶

Funguje aj bez internetu

Premenovanie súborov nepotrebuje internet a s File Renamerom ho ani nikdy nebude potrebovať. Funguje úplne offline, kdekoľvek.
