How to pushd mutliple folders on Windows batch

How can I include multiple paths? Like for example:

pushd C:\Users\Downloads\back\dotNet 
      C:\Users\Downloads\back\MySQL

And exclude every file with extension .log

7za.exe a -tzip -mx5 -x!\*.log* "C:\Users\Desktop\Downloadbak-%TODAY%.zip"
popd


ECHO.

PAUSE

Solution

There are actually 2 questions here:

pushd
7z(a).exe

Regarding pushd: a simple answer to your question is: It can't be done.
pushd (push directory) and popd (pop directory) operate on a stack like structure - operations on a stack are push and pop

push has an argument and inserts it over the current stack top (the last element inserted), if any, and thus that becomes the stack top
pop simply takes the top of the stack out and making the next element of the stack (if any) its top

So:

pushd inserts the current dir (%CD%) on the top of an internal stack and changes the current directory to the directory that it got as an argument
popd changes the current directory to the top of the (same) internal stack and also removes it from the stack

But your desired behavior can be achieved by a sequence of pushd / popd commands, and there is one aspect that needs to be clear: pushd and popd commands order is reversed - explanation below:

Let's assume that the internal stack is empty: you're located in ${DIR1} (this is a directory full path somewhere in your filesystem). As a note, Nix style variables (${...}) are just (directory) placeholders:

You execute:
```
pushd ${DIR1}
```
This inserted ${DIR1} in the stack and changed your current dir to ${DIR2} (this is where you are located). Then you execute:
```
pushd ${DIR3}
```
This inserted ${DIR2} on the stack (on top of ${DIR1}) and changed the current dir to ${DIR3} (this is where you are located). Now, you do your operations, and want to get back, so you execute:
```
popd
```
This takes out ${DIR2} (the last one that was pushded) from the stack and changes the current directory to it (you will be located in ${DIR2}). And finally when executing again:
```
popd
```
${DIR1} is being removed from the stack (and thus the stack becomes empty - as it was at the beginning) and it changes the current directory to it, so you will be located in ${DIR1} just like before the 1^st pushd command

Now, regarding the 7zip executable (I see that you typed 7z a.exe, while on my computer is 7z.exe (just installed it)):

It seems that your filter is perfectly fine, but it only strips the log files from he current directory, the sub directories seem to ignore the -x flag. So, I tested and it turns out that if I pass -r (recursive) it will also strip out all the .log files from sub-directories (although I can't explain why your pattern doesn't work with directories - maybe it only refers to base file names?).

Here's the command (notice that I removed the \ before the *):

7z.exe a -tzip -mx5 -r -x!*.log somefile.zip
