What is a FE_TMP file? An FE_TMP file is a temporary file created by Mi File Explorer, a file manager for Xiaomi smartphones. Mi File Explorer creates a new FE_TMP file whenever a user moves, copies, or deletes a file. In most cases, Mi File Explorer automatically deletes FE_TMP files after completing the related file operation. If Mi File Explorer fails to delete an FE_TMP file, it can cause the user's phone to believe their SD card is invalid.

More Information Mi File Explorer (also called Mi File Manager) is a file manager designed for Xiaomi MIUI smartphones. It allows users to browse, open, copy, delete, and share their files. In some cases, when a user moves, copies, or deletes a file with Mi File Explorer, the program creates and does not delete an FE_TMP file. This issue can cause Mi File Explorer and the MIUI operating system to believe the user's SD card has become corrupted. To resolve this issue, use a different file manager or a file recovery program (such as TeamWin Recovery Project) to delete any FE_TMP files stored on your SD card. (Often, Mi File Explorer places FE_TMP files in SD cards' root directory.) To avoid this issue recurring, you may want to use a different file manager to move, copy, delete, or share files in the future. NOTE: If you use Mi File Explorer to move a file to another storage device (such as a USB flash drive), Mi File Explorer may also create an FE_TMP file on that device.
