The General tab controls update checks, multipart transfer behavior, and default ACL handling for uploaded or overwritten files.
TntDrive General Options
General
Automatically check for software updates - when enabled, TntDrive checks for new versions daily. If an update is available, the application can notify you so you can download the current installer.
File Transfer Settings
Enable multipart uploads with part size (in megabytes) - uploads large files in separate parts instead of sending them as one request. This usually improves transfer speed and reliability for large files.
Multipart upload part size - specifies the size of each uploaded part. Smaller parts may increase parallelism, while larger parts reduce the number of requests sent to the storage service.
Enable multipart downloads with part size (in megabytes) - downloads large files using multiple parts, which can improve throughput when the storage service and network connection allow it.
Multipart download part size - controls how much data is downloaded per part when multipart downloads are enabled.
Permissions
Inherit permissions from parent bucket - uploaded files inherit the ACL permissions of the parent bucket.
Preserve permissions when overwriting existing files - keeps the permissions already assigned to the existing object during upload or copy/move operations.
For buckets created with modern Amazon S3 ownership and public-access defaults, ACL-related options may require additional bucket configuration.
Proxy
The Proxy tab configures how TntDrive connects to storage endpoints when your network requires a proxy server.
TntDrive Proxy Options
Proxy
Proxy mode - chooses whether TntDrive connects directly, detects proxy settings automatically, or uses the proxy server specified below.
Proxy server - the host name or IP address of the proxy server.
Proxy port - the TCP port used by the proxy server. The default value is usually 8080.
Proxy server requires authentication - enable this option when the proxy requires credentials.
User name - the account name used for proxy authentication.
Password - the password used for proxy authentication.
Domain - optional Windows domain or authentication realm required by some corporate proxies.
Bandwidth Throttling
The Bandwidth Throttling tab limits how much bandwidth each transfer thread may use. This is useful when mapped-drive traffic should not consume the whole connection.
TntDrive Bandwidth Throttling Options
Bandwidth Throttling
Enable bandwidth throttling with max transfer rate per thread (KB/s) - turns on transfer rate limiting for active transfer threads.
Max transfer rate per thread - specifies the limit in kilobytes per second for one thread. Total usage depends on how many upload or download threads are active at the same time.
Data Integrity
The Data Integrity tab enables checksum validation for uploads and downloads. These checks help detect transfer or storage corruption when working with Amazon S3 and Amazon S3 compatible storage.
TntDrive Data Integrity Options
Data Integrity
Check data integrity during file upload - calculates a checksum before upload and sends or stores checksum data when supported. This gives the storage service or TntDrive a value to verify later.
Checksum algorithm - selects the checksum type used for upload verification. SHA-256 is the recommended default for most modern Amazon S3 and Amazon S3 compatible storage providers.
Check data integrity during file download - verifies downloaded data against available checksum metadata or response headers.
Data Integrity Check Mode for Downloaded Files
Flexible - accepts downloaded files when checksum information is missing or cannot be used.
Strict - requires usable checksum information and treats files with missing or invalid checksums as corrupted.
The Queueing tab limits how many upload, download, and background tasks may run at the same time. Use these settings to balance throughput with CPU, disk, and network usage.
TntDrive Queueing Options
Queueing
Maximum number of concurrent uploads - sets how many upload tasks may run simultaneously.
Maximum number of concurrent downloads - sets how many download tasks may run simultaneously.
Maximum number of other concurrent tasks - limits non-transfer tasks, such as deletions, permission changes, cache operations, and similar background work.
Interface
The Interface tab controls tray behavior, whether the event log is shown at startup, and the application color theme.
TntDrive Interface Options
System Tray
Always show TntDrive icon in system tray - keeps the TntDrive tray icon available while the application is running.
Minimize to system tray - hides the main window to the tray when it is minimized.
Show event log - opens the event log panel automatically when TntDrive starts.
Color Theme
Light - uses the light interface theme.
Dark - uses the dark interface theme.
System - follows the Windows application theme automatically.
Logging and Error Handling
The Logging and Error Handling tab controls event log files, log verbosity, and retry behavior after failed tasks.
TntDrive Logging and Error Handling Options
Logging
Save event log to file - writes event log messages to log files on disk.
View log files - opens the folder that contains saved TntDrive log files.
Remove log files older than (days) - deletes old log files automatically after the configured number of days.
Verbosity level - selects how much detail TntDrive writes to the log.
Verbose - records detailed diagnostic information.
Brief - records a compact operational log.
Errors and Warnings Only - records only problems that need attention.
Error Handling
Maximum retry attempts for failed tasks - controls how many times TntDrive retries a failed task before leaving it failed.
Delay (in seconds) between retry attempts - controls how long TntDrive waits before retrying a failed task.
Advanced
The Advanced tab contains file-system and security settings that affect temporary file storage, disk access, and SSL/TLS certificate validation.
TntDrive Advanced Options
File System
Folder for temporary files - specifies where TntDrive stores temporary files used during operations that need local intermediate data.
Allow parallel disk access for hashing and encryption - lets TntDrive perform disk reads in parallel for hashing and encryption work. Enable this only for fast SSD storage.
Security
Bypass SSL/TLS validation (program restart required) - disables certificate validation and trusts all certificates. Use this only for troubleshooting or controlled test environments.
