Compressing large volumes of data into a single extractable file is necessary, but it makes it harder to send the information over the internet. File compression software gets around this problem by archiving the original compressed file as numerous smaller, sequentially labeled parts.

These divisions may then be readily transported to their final destination one by one. When they arrive, the end-user may use the same program to merge the files and extract all of the original data at the same time.

ALZip, a program by ESTSoft, archives and compresses files in the ALZ format. Its partition archive files are labeled A00, A01, A02, and so on. If all of the sequential file partitions are available, as well as an initial ALZ file, the original contents may be recovered. When ARJ software unpacks the data, it uses the A00 file extension in the same way as ALZip does.
