File Manager cannot find my external SD card?

File Manager can manage external SD(MicroSD) card. The only problem is that user needs to find out the path to external SD card.

Following device users should not have this problem:

The device which has large ROM and does not have SD card slot, such as Galaxy Nexus, Nexus 7, HTC One S, One X, etc.
The device which has limited ROM and supports moving apps to SD card, such as HTC Wildfire S, Desire HD, Sensation 4G, Xperia arc S, etc. The default path to File Manager on this kind of devices should be the external SD card.

Following kind of device users may have this problem:

The device which has both large ROM and SD card slot, commonly does not support moving apps to SD card. This kind of devices use a partition of the internal storage for the external storage, the default path to File Manager on this kind of devices should be the internal storage partition instead of external SD card.
Such as: Galaxy S3, Note, Note2, Xperia acro S, Motorola Xoom, etc.

For the 3rd type of devices, there will be an "SD Card" button appear in toolbar if File Manager detects external SD card besides your internal storage. You can click it to navigate to external SD card if mounted.

If your device is the 3rd type device and "SD card" button does not show up on your device, please contact support@rhmsoft.com to get more specified support.

File Manager cannot support USB storage(OTG)?

File Manager can access USB storage using OTG.

If your device directly support to mount USB storage, you just need to find out the mount point to the USB storage, such as "/storage/usbdisk", etc.

If your device does not support OTG, you may need some additional work. As far as I know, currently only rooted devices can support OTG by installing some USB mount applications, such as "StickMount". Then your USB storage can be mounted to your device, the path may like "/sdcard/usbStorage/xxxx/". You can navigate your File Manager to this path to access your USB storage. You can find more information by Google or from "StickMount" application introduction.

How do I transfer files to SD card of my device?

File Manager can manage external SD card the same as standard folder. The major step is to find out the path to external SD card, please refer to 2nd question in this page.

After you know the path to external SD card, then following steps are straightforward:

You can long click on the file which you want to transfer to SD card, and choose "Copy" menu item to choose it as source file. You can also enable multi-selections mode to select and copy multiple files at the same time.
After choose copy action, there will be a new button in the toolbar named "Paste". Now you can navigate to the path to external SD card (If there is "SD Card" button in toolbar, you can click on it to navigate to SD card directly).
You can choose the desired folder under SD card as the paste target folder. Then you can click "Paste" button from toolbar to start the file transfer. You will see a popup dialog which indicates the transfer progress.

How to set/reset default application for specified file type?

File Manager is using Android built-in mechanism to associate file type and applications.

If you want to set the default application to open specified file type, such as "*.bmp" file, you just need to click "Always" button or check "remember my choice" in application chosen dialog.

If you want to change the default application which is used to open specified file type, you need to go to Android settings->apps, find out the current default application and in the application page, click "clear default" to release current file association.
