JumpDrive C25i Lexar media manager app FAQs - discontinued

Getting started Which Lexar products work with the Lexar Media Manager app? Currently, the Lexar Media Manager app works with the Lexar JumpDrive® C25i flash drive. For a listing of products that the Lexar Media Manager works with, check out the compatibility list on www.lexar.com/support. To determine if this app is right for your Lexar iOS-compatible product, visit your product’s information page on lexar.com. How do I get the Lexar Media Manager app? You can download the app from the App store®. What is the difference between the Lexar Media Manager app and the Lexar Mobile Manager app? I see both on the App Store. The Lexar Mobile Manager app is an app that is compatible with older Lexar products, and not with more recent Lexar iOS-compatible products. For more information on which app is compatible with your Lexar product, refer to the compatibility chart on the Lexar support page at www.lexar.com/support Is the Lexar Media Manager available for Android? No, the Lexar Media Manager is an app that works with Apple® iOS products. Compatibility Which Apple devices are compatible with the Lexar Media Manager app? The app is compatible with iPhone 5/5s/5c, iPhone 6/6s/6s Plus, iPhone 7/7 Plus, iPhone SE, iPad mini 2/3/4, iPad 4, iPad Air 1/2, iPad Pro 9.7 inch/12.9 inch, and iPod touch (sixth generation). Which music and video file formats are compatible with the Lexar Media Manager? Files supported: Music—MP3/CAF/AAC/AIF/WAV/AIFF/M4A. Video—AVI/FLV/MP4/MOV/M4V/MKV/MPG/RM/RMVB/WMV/3GP Note: Does not support streaming of DRM-protected content. Contact your content provider for details and restrictions. Will the Lexar Media Manager app work with other manufacturer’s flash drives? No, the Media Manager app will only work with Lexar products. Using the App Home Screen Does the app work the same on a tablet as on an iPhone? The functionality of the app is the same. There may be slight differences in navigation due to the available screen size of the tablet vs. the iPhone format. Phone navigation – Encrypt (or Decrypt), Rename, Get info, Zip, and Zip and Lock are all located under “More.” Tablet navigation—More functions visible On the Home screen, what does the percentage and the “free” refer to under Internal Storage and External Storage? The home screen displays your available storage on your device (phone/tablet) under Internal Storage, and your available storage on your connected Lexar product under External Storage. Why can’t I see all the files on my phone/tablet when I tap on “Internal Storage” on the Home screen. Tapping on Internal Storage on the Home screen provides access to only those files stored in the app’s internal storage, and does not provide access to all files on your device. What does External Storage refer to? External storage is the storage on your connected Lexar iOS-compatible device. Why does External Storage say N/A? External Storage will display N/A until you connect your Lexar iOS-compatible device. I have added files to my external storage device and the storage available display has not changed. How do I get it to refresh? Tap on the refresh icon in the upper right corner of the Home screen to immediately refresh your available storage display. What do the individual icons on the Home screen do? Tapping on “Music,” “Photos,” “Videos,” or “Documents” will display only those file types, whether stored in Internal Storage (within the app), or in External Storage (on your Lexar device). Backup will take you to the backup function, and camera will launch the app’s camera. How do I modify the app’s settings? To access the Settings screen, tap on the settings icon located in the upper right corner of the Home screen. Setting Screen What does turning the support setting to the “ON” position do? Turning on the Support function creates a new email to the Lexar support team from the primary email address linked to your device. It will automatically include your app specifications, making it easy for you to send an email to get answers based on your version of the app. What is required for TouchID to work with my app? This function will only work with devices with TouchID. TouchID must be available and enabled on your device. Do I need to toggle the Auto Backup function to the “ON” position in order to do any backups? The Auto Backup function in the Settings screen will allow automatic backups of photos, contacts, or both, every time your Lexar iOS-compatible product is connected to your device. You can still perform manual backups at any time, regardless of whether the Auto Backup function is turned on or not. Which files will Auto Backup back up to my Lexar iOS-compatible product? This function will back up photos and videos that are stored in your camera roll, and contacts stored on your device. It will not back up any files saved in the app’s Internal Storage. Do the camera setting controls on the Settings screen control my device’s camera? The functions within Camera Settings on the app’s Settings screen control the settings for videos taken with the app camera only. Automatic and Manual Backups When running Auto Backup, will I be given the option to automatically delete the files after update? No, the automatic backup function does not automatically delete files after backup. To do this, select manual backup of photos. When doing a manual backup of photos on my iPhone and selecting “Yes” to the message asking whether I want to delete the photos after backup, why does the space available on my Internal Storage display not show a difference? For safety and in case of accidental deletion, your iOS device keeps a folder in your Photo Album of “Recently Deleted” photos. Your deleted photos will be in this folder for 30 days, at which time they will expire. You can delete them immediately by navigating to the folder and selecting all (or some) of the photos and delete them immediately. Once the photos are removed completely from your device, you will notice the storage space percentage and free under Internal Storage on the Home screen will reflect the updated storage availability. Music Why can’t I move all of my music files to my external storage? Only music files not protected by Digital Rights Management (DRM) can be managed with the Lexar Media Manager app. Files that are protected may show up on your music file list in the app, but they will appear greyed out, and you will not be able to select those files. Encryption/Decryption I’ve lost my password for File Lock (Encrypt) and/or App Lock. How do I retrieve it? Your password is unique to you and Lexar does not keep a copy of it, so there is no way to retrieve a copy of it when it is lost. It’s a good idea to choose a password you know you’ll remember, or jot it down somewhere so you can access it if you forget it. Additional Resources I still have questions about the app. Where can I go for help? You can download the full Lexar Media Manager User Guide, view warranty information, and find other support information at www.lexar.com/support

JUMPDRIVE® 闪存盘 常见问答

Lexar U盘不支持 4GB 或更大的文件,这是什么原因? 要传输大于 4GB 的文件,必须具有 NTFS 或 exFAT 文件系统。 U盘出厂时的默认的文件系统是FAT32,不能处理大于 4GB(准确地说是比 4GB 小一个字节)的单个文件。 请按照下面的步骤,使用 NTFS 文件系统来格式化U盘: 警告,U盘上的所有数据将会丢失!继续之前,请备份U盘上的数据。 1.打开”我的电脑”(Vista 和 7 中为”计算机”)。 右键点击Lexar U 盘并选择”格式化”。 2.从文件系统下拉列表中选择 NTFS 或 exFAT。 3.选择“快速格式化”作为“格式化”选项,然后单击“开始”。 注: 如果 NTFS 不是可用的选项,请关闭”格式化”窗口并按步骤 4-9 操作。 4.右键单击“我的电脑”(Vista 中为“计算机”),然后选择“属性”。 5.选择“硬件”选项卡,然后单击“设备管理器”。 6.展开磁盘驱动器,然后右键单击Lexar U 盘。 选择“属性”。 7.单击“策略”选项卡,然后选择“为提高性能而优化”。 8.单击“确定”。 9.重复步骤 1-3。 请注意,MacOS 10.6.5 支持对 exFAT 格式的驱动器进行完全的读写访问。 MacOS 仍然只能对 NTFS 格式的驱动器进行只读访问。有些设备(MP3 播放器、数码相框等)无法读取 NTFS 或 exFAT 文件系统。此外,Windows XP 和 Vista 需要更新才能访问 exFAT。 能否将Lexar U盘,作为可启动的 USB 设备? 虽然可以从U盘启动,但这并不是Lexar 支持的功能,U盘原本是作为存储盘来使用的。 Lexar U盘否具有写保护功能? Lexar U盤不具写保护功能。 如果您使用 U 盘是遇到写保护消息,请检查以下各项: 1. 确认您被允许对可移动存储设备进行写入。 操作系统中可能有安全设置禁用对可移动存储设备的写入访问。 2. 确认您是否在使用U盘时启用了第三方软件的写保护。 如果以上都不是,那么 U 盘可能有故障。 请与售后服务部门联系获取进一步的帮助。 USB3.0与USB3.1一样吗? USB3.1是USB协会制订的规范,USB3.1可以分为USB3.1 Gen1以及USB3.1 Gen2: USB3.1 Gen1 (SuperSpeed): 最高理论传输速度为5 Gb/s(等同于USB3.0)。 USB3.1 Gen2 (SuperSpeed+): 最高理论传输速度为10 Gb/s。 实际速度依产品规格为主。 U盘产品在计算机认不到,遇到这样的状况应该如何处理? A请先检查认不到的那台计算机USB插槽功能是否正常,以及是否挂载对应的随身碟驱动程序,若排除插槽功能以及驱动程序问题后仍然认不到,请联系售后服务。 有些金属壳U盘产品,使用后摸起来热热的,这是正常的吗? 由于金属材质的U盘外壳相较于塑料材质的U盘外壳,更容易传导温度,所以使用后温度与塑料材质的U盘相比较高,此属正常现象,请安心使用。 USB1.0/USB1.1/USB2.0/USB3.0/USB3.1的传输速率各是多少? USB 1.0的最高理论速率为1.5 Mb/s传输数据*。 USB 1.1的最高理论速率为12 Mb/s*传输数据*。 USB 2.0的最高理论速率为480 Mb/s传输数据*。 USB 3.0 及 3.1(Gen 1)的最高理论速率为5 Gb/s传输数据*。 USB 3.1(Gen2)的最高理论速率为10 Gb/s传输数据*。 *实际速度根据不同产品而有不同 什么是USB type-C接头? USB Type-C,又称USB-C,是一种通用串行总线(USB)的硬件接口形式,外观上最大特点在于其上下端完全一致,与Micro-USB相比这意味着用户不必再区分USB正反面,两个方向都可以插入。 USB Type-C支持OTG功能,即在没有主机(例如个人计算机)的情况下,便携设备之间可直接实现数据传输,可支持到USB3.1规格,亦可向下兼容。 什么是Micro USB接头? 在许多智能型手机和平板计算机上替代Mini-USB,比Mini-USB插头高度减半,宽度相差无几。 Micro-USB标准支持目前USB的OTG功能,即在没有主机(例如个人计算机)的情况下,便携设备之间可直接实现数据传输,兼容USB1.1和USB 2.0规格。 U盘如何正确使用? 请将U盘 USB接头插入计算机对应的USB接口,计算机会自动跳出文件夹窗口。 若不使用U盘时请先「安全地移除硬件」并选「退出USB DISK」,之后再将U盘拔除计算机端。 要如何才能保护我U盘的数据呢? 使用完USB装置时, 拔除USB装置前请正确执行「安全地移除硬件」的动作。 如果是重要数据请养成做备份在其他储存装置的习惯,因为任何储存装置都有使用寿命无法”永久”的保存数据。 Q: USB 2.0 跟 USB 3.1在储存数据上会有差异吗? A: USB2.0在数据传输上理论速度会较USB3.1来的慢,但在储存数据的功能没有不同。 且USB3.1标准的U盘或是插槽可以向下兼容USB2.0的接口。 计算机只有USB 2.0 的插孔,能使用USB 3.0的U盘吗? USB3.0能够向下兼容USB2.0规格,故不影响读写数据的功能,但将USB3.0 U盘使用在USB2.0插槽上会受到传输速度的限制。 要如何查看我的U盘容量呢? 请至「我的计算机」中,在U盘图标上点右键再点选「内容」,即会显示随身碟装置的容量。 亦可透过「计算机管理」中的「磁盘管理」来确认U盘的容量。(不同电脑系统,功能名称可能不同) U盘是通过什么方式来储存数据? U盘是透过NAND Flash当作储存数据的组件,NAND Flash透过充电以及放电(写入/抹除)的方式来存放数据这类储存装置拥有比传统硬盘重量轻、体积小、省电、不怕震动以及效能更好等优势。 如何更改U盘的名称? 在U盘图标点选右键「重新命名」即可更改U盘名称,或透过格式化的方式在「磁盘区卷标」的字段更改名称,格式化前请先将数据备份,以免数据因格式化被删除。 在传输数据的过程中不小心拔掉U盘会发生什么事? 请注意避免在数据传输过程中拔掉U盘,这样的动作会造成档案在传输过程中数据遗失,甚至可能造成U盘的功能异常。 若使用完U盘,请先「安全的移除装置」再将U盘拔除插槽。


JUMPDRIVE® FINGERPRINT F35 闪存盘 常见问答

我的USB闪存盘插上后,为什么电脑不能识别? 请重新插入闪存盘,然后再次运行应用程序。 为什么闪存盘显示的容量比总容量少? 总容量分成公共分区和安全分区两个部分。用户在指纹认证后,可以更改安全分区的大小。 能不能通过智能手机访问闪存盘的安全分区? 使用智能手机时,只能访问公共分区。 为什么不能将大于4GB的文件保存到闪存盘上? F35的初始格式是FAT32;在传输大于4GB的文件时,您需要将闪存盘重新格式化为exFAT。请注意,重新格式化会导致您丢失闪存盘上的所有文件。但是,指纹应用程序本身不会被清除掉。 指纹应用程序兼容哪些系统? 指纹应用程序可以在Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10中运行。 要设置管理员/用户帐户或更改闪存盘分区大小,需要满足什么最低要求? 指纹应用程序要求Windows XP及更高版本或者Mac OS 10.10.x及更高版本。需要使用指纹应用程序来设置任何帐户或更改分区大小。 如果我的Windows、Mac OS或Linux版本较旧,还能访问公共分区和安全分区吗? Windows、Linux和macOS可兼容闪存盘的基本使用。 为什么安全分区会在15分钟后消失? 出于安全目的,安全分区经过专门设计,会在无活动状态持续15分钟后关闭。要重新访问安全分区,只需通过感应器认证已授权的指纹,它就会重新打开。 Lexar F35 Fingerprint闪存盘采用哪一种加密类型? 加密基于256位AES方法。指纹数据通过FP IC生成的专用UID存储在闪存盘中。由于指纹数据和指纹算法是分开的,当闪存盘被强行拆解后,保存在安全分区中的数据会丢失。 我有多少次机会尝试输入正确的管理员密码? 如果用户连续输入错误的密码超过254次,F35会启动自毁过程。USB闪存盘中的所有数据都会被清除,并且只有通过重新下载固件才能恢复。 为什么我将手指放到指纹感应器上数次后,还是不能访问安全分区? 请确保手指和感应器都干净且干燥。如果不行,请尝试重新插入闪存盘。
