IFM - improved file manager



The IFM is a web-based filemanager, which comes as a single file solution using HTML5, CSS3, JavaScript and PHP. You can test a demo here.


The IFM uses the following resources:


  • create/edit files and directories
  • copy/move files and directories
  • download files and directories
  • upload files directly, remotely via URL or per drag & drop
  • extract archives (tar, tgz, tar.gz, tar.bz2, zip)
  • change permissions
  • image preview
  • simple authentication (LDAP via ldap_bind possible)


  • Client
    • HTML5 and CSS3 compatible browser
    • activated javascript
  • Server
    • PHP >= 5.6
    • extensions
      • bz2
      • curl (for remote upload)
      • fileinfo
      • json
      • ldap (only if LDAP based authentication is used)
      • mbstring
      • openssl (for remote uploads from https sources)
      • phar
      • posix
      • zip
      • zlib


Just download the latest release of the IFM. You can find it here. You can choose between the CDN version (dependencies like bootstrap, jquery etc. are loaded via CDN) or the "simple" version, which bundles all these dependencies.

The minified versions (*.min.php) are zipped via gzip. These versions are not recommended; if the filesize of the IFM is an issue for you, consider using the CDN versions.

Security information

The IFM is usually locked to it's own directory, so you are not able to go above. You can change that by setting the root_dir in the scripts configuration.

By default, it is not allowed to show or edit the .htaccess file. This is because you can configure the IFM via environment variables. Thus if anyone has the ability to edit the .htaccess file, he could overwrite the active configuration. See also.


  • e - edit / extract current file
  • hjkl - vim-style navigation (alternative to arrow keys)
  • g - focus the path input field (i.e. "goto")
  • r - refresh file table
  • u - upload a file
  • o - remote upload a file
  • a - show ajax request dialog
  • F - new file
  • D - new directory
  • cm - show copy/move dialog
  • / - search
  • a - ajax request
  • n - rename file
  • Space - select a highlighted item
  • Del - delete selected files

See authentication.


The docker image is based on the official php docker images (alpine version) and exposes port 80.


Build the image with this command in the top source dir:

docker build -t ifm .

Afterwards you can start the docker container as follows:

docker run --rm -d --name ifm -p 8080:80 -v /path/to/data:/var/www ifm:latest

Specify user/group

By default IFM runs as user www-data (uid/gid 33). If you need to change that, you can set the UID and GID with the following environment variables:

docker run ... -e IFM_DOCKER_UID=1000 -e IFM_DOCKER_GID=100 ifm:latest

Other configuration

The script is located at /usr/local/share/webapps/ifm/index.php. By default the root_dir is set to /var/www, so you can mount any directory at this location. If you want to bind the corresponding host directory, you can do the following:

docker run --rm -i -p "8080:80" -v "/var/www:/var/www" ifm

The scripts configuration can be changed by adjusting the corresponding environment variables. For example:

docker run --rm -i -p "8080:80" -v /var/www:/var/www \
  -e IFM_AUTH=1 -e IFM_AUTH \
  -e IFM_AUTH_SOURCE="admin:$2y$05$LPdE7u/5da/TCE8ZhqQ1o.acuV50HqB3OrHhNwxbXYeWmmZKdQxrC" \

You can get a complete list of environment variables here.
