Index Your Files is a portable, cross-platform utility that can index, import, export, save, and search folder/file information.
Index Your Files works by creating individual databases for an individual/computer. You can also create databases for the whole network allowing you to know the location of the information you need efficiently. It has access to folders and files on every network computer as long as it is powered on. But even if the machine is off, you can still access file names.
It can index Windows, Linux or Mac Disk, CD, Networks, etc., regardless of whether it is NTFS, FAT32, FAT16, EXT4, etc., as it indexes everything recognizable to the OS.
The Linux download is available at the author's site.
Index Your Files also allows you to share your databases; no matter the OS, the databases were created and can be shared across the supported platforms.
