4 Free Tools To Split Large Files And Join Smaller Parts For Videos, PDF And More

Why should one want to split and recombine files? For instance, think of a file of 50 Mb, and try to send it to a friend, post it in a newsgroup or upload it to a Website or FTP server. It is usually easier to send/receive, upload/download smaller parts than handle the entire file in one go. The other reason is you can easily hide important files by splitting them into 2 files and save them in 2 different hard disks, making it impossible to be stolen.

1. GSplit

GSplit is a free reliable file splitter that lets you split your large files, such as compressed archives, text and log files, backups, disk images, video and document files…, into a set of smaller files called pieces.

• Let you select from two basic file splitting options: disk spanned (split into a set of files varying in size auto-calculated by GSplit based on available free disk space and saved immediately to spannable removable disks) or blocked (split into a set of same sized split files). You may enter the size for each piece file, the number of pieces you want to obtain, or the number of lines/occurrences of a pattern by piece.split files
• Make pieces Self-Uniting: GSplit creates a small stand-alone executable file that will put all of the pieces back together. This executable provides your users with an intuitive Windows interface whose appearance can be customized according to your needs. Thus GSplit is not required in order to restore the split file.
• Store file properties like file dates and attributes, and restore them contrary to batch files.
• Perform fast checks (size, offset, CRC32) in order to detect file corruption and to give you the assurance that your files are successfully restored by your users. When a piece is corrupted, you are notified about it, so you just need to get a new copy of that piece, not the whole set.
• Split very large files, with sizes higher than 4 GB, without any problem.
