Frequently Asked Questions
What is "Mask Filenames"?
This obfuscates the internal file structure. Instead of seeing 'Aadhar_Card.pdf', anyone viewing the archive will only see 'protected_item_1.pdf'.
Is RAR better than ZIP?
RAR generally provides better compression than ZIP, particularly for larger file sets, and supports higher-level encryption standards.
Can I open this .rar on mobile?
Yes. Most modern mobile file managers support RAR files. Alternatively, use the OTechy RAR Decryptor tool on any mobile browser.
Does OTechy store my files?
No. Zero data ever touches our servers. The entire logic runs inside your device's browser sandbox for 100% privacy.
