ACAPsoft Chop File Splitter 1.6

This compact program is for splitting large files (including ones larger than 4 GB) down to the byte level for easier distribution. (Or if you are a spy, you can divide a file up and even semi-encrypt it for security reasons...) It's also useful for splitting up blocks of stream data. Using either a normal window or a wizard interface, files can be split by either the number of files that you want, the maximum file size, or you can use preset common sizes for EMailing, floppies, Zips, CDs, etc... The program can Chop and UnChop files in Wizard and normal interface, and supports file time and attributes preserving, CRC to detect file corruption, command line operation and even simple encryption. In addition, if size is an absolute priority and you do not need any of the more advanced features of Chop, you can instead set Chop to create a very small BAT file which will rebuild the file without Chop.

Feature List:

* Chop is written in 100% Assembly Language and is very small and memory efficient. The program itself is under 100KB!
* Chop can be easily run as a portable app from, for example, a USB key; it does not even need to be installed! Simply select "Extract" from the installer and then copy "Chop.exe" wherever you want!
* Chop can split files greater than 4GB; we have personally tested 12GB files.
* CRC is used to detect file corruption. In Chop file mode this is handled automatically (if enabled) and will notify you of any differences found.
* Has 18 quick set sizes for common media formats like CDs, DVDs and USB flash drives.
* The output size can be set by size or number, and a slider bar is provided to assist you to find the desired balance.
* Output can be in the form of a "Chop" file (.chp) or as a simple file chunk.
* File chunks are un-chopped using batch files (.bat) which are compatible with any Windows version.
* Chop files allow the usage of extra Chop functions including CRC, encryption and adding a description.
* Whatever output format you choose Chop can be used to Un-Chop the files. Chop can also be used to Un-Chop other files providing they are numbered in the same way that Chop does.
* Chop has the option of being associated with .chp files to make un-chopping easier.
* Files can also be Chopped and Un-Chopped via command line instructions.
* All settings are saved for convenience.
* Multi-user setups are supported and Chop will run without any problems on a low privilege system and Windows Vista.
* The encryption function uses a simple 32 character XOR technique. This is not very secure and is designed only to prevent casual viewing of any personal data.
