.__A File Extension
File TypeFile Splitter & Joiner Encrypted File
What is a __A file?
Split archive file created by File Splitter & Joiner (FFSJ), a utility used to break up files into smaller parts and reconstruct them; contains the first part of a multi-part encrypted archive; used for storing password-protected data in smaller segments.
FFSJ uses the extensions ".__a," ".__b," ".__c," ..., "._aa," "._ab," etc. when creating encrypted split archives. For unencrypted archives, it uses the extensions ".001," ".002," etc. All split archive files are created with the same file size. Split archives can be created and reconstructed from multiple directories.
NOTE: FFSJ actually stands for "Fastest File Splitter & Joiner" even though the program name is "File Splitter & Joiner."
