Frequently Asked Questions
Dexxer is an offline macOS application designed to provide fast, secure, and comprehensive file indexing and search capabilities for external storage devices. The following FAQ offers detailed information for users, enterprises, and technology evaluators.
What is Dexxer?
Dexxer is a dedicated offline file indexing and search system for macOS, engineered to allow users to locate files stored on external hard drives, SSDs, USB drives, SD cards, network-mounted storage, and archival media — even when those devices are not physically connected.
Dexxer creates a local metadata index of each drive, enabling instant search across multiple storage volumes without requiring cloud access or device mounting.
How does Dexxer index external drives?
Dexxer performs a complete scan of the connected drive’s directory structure, reading file names, paths, sizes, extensions, creation dates, modification dates, and relevant metadata.
It then generates a local, persistent index stored exclusively on the user’s Mac.
Key attributes:
No files or metadata leave the device
No cloud processing or third-party servers
No background trackers or analytics
Indexes update only upon user action
This ensures complete privacy and maximum performance.
How does Dexxer enhance workflow efficiency?
Dexxer eliminates the need to repeatedly mount or reconnect external drives to locate files. This is particularly valuable for professionals managing large-scale archives, including:
Photographers working with RAW image libraries
Videographers managing multi-terabyte footage sets
Audio engineers with extensive sample packs
Digital content creators storing project backups
Developers maintaining historical project branches
Media agencies with distributed storage systems
Dexxer reduces search time, minimizes workflow interruptions, and simplifies asset retrieval.
Does Dexxer upload my data or require cloud connectivity?
No. Dexxer is a 100% offline software application.
Dexxer does not:
Upload files
Upload metadata
Store user information in the cloud
Require an internet connection to operate
Use analytics tracking or fingerprinting
Sync to servers or external platforms
This design provides a high-security, non-intrusive environment suitable for confidential assets, client-sensitive files, and regulated industries.
Which operating systems does Dexxer support?
Dexxer is currently available for macOS only.
Support for Windows (PC) is planned for a future release, along with potential Linux compatibility.
Which storage devices are compatible with Dexxer?
Dexxer supports any storage medium recognized by macOS, including:
External HDD
External SSD
NVMe enclosures
USB flash drives
SD and microSD cards
RAID volumes (macOS-mounted)
NAS volumes accessible via Finder
Legacy devices: Zip disks, Floppy disks, CDs/DVDs
If macOS can mount the device, Dexxer can index it.
Can Dexxer search drives that are disconnected or offline?
Yes. This is Dexxer’s core functionality.
Once indexed, drives can be searched instantly without being connected.
This enables:
Offline search across entire archives
Faster asset recovery
Reduced reconnection cycles
Centralized file discovery
Does Dexxer support high-capacity drives?
Yes. Dexxer is optimized for large-volume data environments, including multi-terabyte drives used by content creators, production studios, and media archives.
Does Dexxer modify or alter any files?
No. Dexxer reads file metadata and directory paths but does not:
edit files
rewrite metadata
modify drive contents
reorganize directories
move or duplicate files
Dexxer is read-only during indexing and search operations.
Does Dexxer include a duplicate file finder?
Yes. Dexxer Pro includes a duplicate file detection system capable of identifying redundant files across multiple external drives. This supports efficient storage consolidation and cleanup.
Where does Dexxer store index files?
Indexes are stored locally on the user’s system at:
~/Library/Application Support/Dexxer/indexes
Indexes remain device-local and are not transmitted outside the computer.
Does Dexxer require an account or login?
No. Dexxer uses a no-account model for maximum privacy.
Dexxer Pro activation uses a license key provided by LemonSqueezy, but no user account or cloud registration is required.
Is Dexxer suitable for enterprise or professional environments?
Yes. Dexxer's offline-first architecture makes it appropriate for:
Creative agencies
Production studios
Photography businesses
Government environments
Corporate archival teams
Legal and compliance teams
Dexxer prevents data leakage by not transmitting any data outside the local machine.
Does Dexxer impact system performance?
Dexxer is lightweight and runs only during indexing or when performing searches.
It does not run persistent background processes or consume ongoing system resources.
Does Dexxer work with macOS Sonoma, Ventura, or older versions?
Dexxer supports all modern versions of macOS, including:
macOS Sonoma
macOS Ventura
macOS Monterey
(Additional compatibility notes will be listed on release pages.)
