TOTALCMD.EXE size

I know I shouldn't do this, but I couldn't restrain myself from checking.
TOTALCMD.EXE has grown significantly since 6.55. But it doesn't have to be so big! Repacking with UPX 2.91 beta and --best --lzma switches gives 875.2 KB executable. Upack ( by default ) - 861.4 KB.

I know about UPX beta. The reason why I still use the old version of UPX is the following: Virus scanners have big troubles checking EXE-packed programs. Most good virus scanners have internal unpackers for UPX, at least for the older established versions. Therefore I will never use a beta where the format still changes, because virus scanners will have big troubles with such new unpackers. I will consider to use UPX 3 when it becomes final.
Of course, some virus scanners never learn to support EXE packers, for example f-prot...

because virus scanners will have big troubles with such ... unpackers
Therefore I suggest to skip over the exe compression in the normal packages and add on default the uncompressed exe. In my case the load of compressed exe is remarkable slow compared with uncompressed exe (because of virus scanner scans the exe before it will be started...). On todays terrabyte harddiscs and on yesterdays gigabyte harddisc there is no need to save 2 megabytes and get some trouble with virus scanners instead. For people who wants/needs an exe compressed file it should be downloadable too or make two packages: one with uncompressed exe and another with compressed exe.
Only my 2cents.

On most machines I work Total Commander starts faster when compressed - because I run it through USB 1.1. And for my pendrive 2 MB makes a difference. I never had any problems with TC and antiviruses.

Just exclude TOTALCMD.EXE file from virus scan (most scanners have such an option).
This will speed up most operations WITHOUT any risk. (TC has an internal CRC check which alerts you if the file is modified)

I agree...
What is the standard memory config these days for PC's?
That must be 1gb allready.
And then we are talking about a few kb's more or less?
It's time to switch over to uncompressed exe with the compressed one on request!

Sorry but only because Harddrives gets bigger and bigger doenst that imply that exe-packers r useless.
I vote for a Compressed Exe in the Installer-Packege for making it as Small as Possible :!
If ppl r unwilling to learn how there virus-scanner work they have to live with it imhuo

I think I missed something. Why don't you like compressed executables? They hardly have any disadvantages.
I'm using them a lot (I use only 1 program over 4 KB that is not compressed) on many computers. Did I have any problems? Once. When I compressed a program I got antivirus alert. So I deleted this copy and changed compressor.

Your argumentation says that you vote for an uncompressed exe file.

Uncompressed exe can be compressed better by the installer compression. That's leads to an installer package as small as possible.

Plz open your mind: not all people have all rights on the machines where they work. It's not funny if I go to a friend, plug in my usb stick, start TCmd from usb stick and her virus scanner told me that totalcmd.exe is quarantined (only for the reason of upx compression)

That's only possible if I have the proper rights.

That's only true for an unmodified totalcmd.exe.

In your special case you choose the compressed version. I didn't vote to omit a compressed version.

It isnt that I dont like compressed executables personaly.
But if there are disadvantages like startup speeds I like a bigger .exe size above slower startup speeds in general.
And I take it a non compressed executable hardly occupies more system memory.

Actually, compressed executable occupies more system memory c.a. 100-500 bytes.
