Luckily Keka can join into 1 file the .001, .002, .... files made by Split function of Total Commander on Windows, but it can't recognize and restore the original file extension.
This information is in the crc file made by Total Commander and it contains the original filename in the first line.
For example if I split a file called blabla.mov with total commander I'll get:
And if I extract them with Keka I'll get a file named "blabla".
In blabla.crc the first line contains the original filaname like this:
So it could be used by Keka.
And maybe .crc files could be automatically recognized by Keka as an extractable format, like in Total Commander.
The crc file contains 2 more lines with verifying datas, use them if you wish:
size=..... - the file size in bytes
crc32=.... - crc checksum
