File Joiner (.001 File Joiner) is a very simple and easy to use application that will combine split files (with extensions: .001, .002, .003, etc.) back into one file. Files with extension .001 (001, 002, ... 00n) are parts of a bigger file that was split so they could be sent over newsgroup, file hosting or some other service which limits maximum size of files that can be uploaded.

Features:
-auto sorting
-auto loading consecutive parts when you open or drag&drop file with extension .001
-auto output file path generator (file "c:test.avi.001" will generate output file path "c:test.avi")
-faster joining with option to append all files to first file
-MD5 and CRC32 hash calculation for output file
-loading files from folder and recursive loading from sub-folders
-option to associate extension .001 in windows explorer, so you can load files by double clicking the file
-progress bar to monitor the join operation (also win7 progress bar in taskbar)
