Split File with TC Android as on desktop

In the desktop version you can split a file in multiple chunks.

Is this possible with the android version?

Need it for of a transport a large video file to my desktop computer, where the only external access is gmail (25 mb limit). (No google drive or other cloud storage options available/No access to desktop through usb cable./No wifi access)

Edit:
Succeeded in emailing the video file by not asking the camera app to email it, instead using trusted TC. It was actually only 14 mb, but the android camera app. insisted that it was to much (which is wasn't ). But the question still stands though!

No, currently there isn't any split function, sorry.

Email standard was designed for text messages and sending files by email isn't a good solution. Binary attachments must be encoded using Base64 which causes about 35% size overhead. For example, when you attach 14 MB file, the email message will be about 19 MB in total.

That's why people first compress files. Of course, it won't help for files internally compressed (video, audio, pictures, pdf etc.), but many archivers can also create multi-volume (f.e rar) or splitted (f.e. 7z) archives. Many archivers have free (possibly with paid additional features) Android versions, available in Google Play, f.e. RAR, 7zipper. They may have even option "Compress and send as email".

Note that some email clients support standard message/partial MIME type. It means that they can split binary attachment and send it as many (maximum 100) email messages. For example, old Outlook Express from Windows XP can do such things. However, more and more modern apps are made for dummies, with bells-and-whistles but buggy or without any useful advanced feature.

As you see, archiver app seems to be the best choice…

Thanks for the answers.
@ghislers:
Just discovered your "Drive for Totalcmd plugin": https://play.google.com/store/apps/details?id=com.ghisler.tcplugins.drive.
That'll do the job (of transferring large files) I imagine.

Thx for the advice. Looking at "zarchiver": https://play.google.com/store/apps/details?id=ru.zdevs.zarchiver. Free/No ads/High count rating. Can extract splitted archives, so might also be able to create them.
Otherwise I'll just write and sideload my own splitter. How hard can it be ;-) (famous last words).

OT:
Is there a section on the board to ask forum interface questions?
Didn't get an email notification of your answers even if email notifications was checked in my preferences (User Control Panel->Board Preferences->Edit notification options->Someone replies to a topic to which you are subscribed).
OHH !!! Just discovered the "Options" check boxes below for this post - "notify me when a reply..." is not checked by default. So that probably overrides the preferences settings.

Many people still prefer RAR because it can create multi-volume archives with independent volumes, which can be unpacked separately even if any volume is missing or broken. For splitted archives (7zip, zip) recovery in such cases is much more complicated or impossible at all. However, there is no free license for RAR compression available, so all free archivers can only unpack rar archives.

In your case it doesn't matter as you want to split files. To keep email messages smaller than 25 MB you should split files to parts with max size 18500 KB.
